Im going to buy a 3dr ex grpA shell on Sunday ( 1 in forsale section )
Basically the owner has describred it as being a shed

So as its cheap enough, I want to have the whole thing shot blasted and start from there. As this would save hours of sanding etc.

Question: is there any down falls in having this done??
And does anybody know of any companies in the Birmingham area that does this?? and the costs involved?

Look forward to your views.
thanx

It'll blast away the rust too, possibly leaving lots of metal work to be done.

Be VERY careful,

The mk2 shown in my sig looked lovely when in one piece but I chose to rip it to bits and get it blasted before I converted it.

Turned out it had more rot than the titanic, I'm still hunting for another shell although may possibly consider just fixing this one as not many old shells are perfect.

i wid have thot that was a good thing,save finding problems later

Try Central blast cleaning in Banbury

Pro's : The shell will be back to bare metal which means easier to repair/paint

Con's : Its shows where its got to be repaired, It can warp panels, It can be costly, Its a shitty job if you do it yourself, It wont remove rust all together but it takes away the vast majority of it

As above they must use the correct media and pressure or it will ripple every panel.

Have heard a glass bead would be needed for this type of thing. Dont mind any rust being exposed as this is one of the points in having it done, although the shell is not at all rotten, just very tatty.

Also would I not need for it to be sprayed with a protective primer of some sort, would the company doing the blasting offer this in there service, as the last thing I want is to be cleaning all that bead from the shell.

HAS to be in Birmingham.

Banbury isnt far from birmingham, worth a try imo, Central Blast Cleaning is a top company and will offer everthing you need

Try www.surfaceprocessing.co.uk

as an alternative to shot blasting

its a chemical dipping process

Tabz @ S.M.Auto's

iTrader: (1)

O.k mate shall get the contact details. thanx

Gaz do you have any experiance's with this? would'nt this make the shell become rotten in places due to chemicals echting into the metal?

I had a very long chat to the owners of the company at the classic car show at the nec , and the process sounds great , they will also put the car in a coat of primer for you

give em a ring they will be tell you all about the process

they are based in dudley , so nice and local for you too

Tabz @ S.M.Auto's

nice one Gaz, just called em but they are closed.
Dont suppose you know the cost involved??

Central Blast Cleaning only use blasting for areas like under the bonnet under neath/inside etc. Places like the roof, wings and what not are stripped by hand to stop the metal being damaged. I got a quote off them before and it was just over a grand for blasting/zinc priming. Not sure if that was the cost with hand stripping the major panels but i know they dont like to blast them. If you're looking for them to strip, repair/replace quite a few panels and repaint it (their paint jobs are top notch) You're looking around the 4-5 grand mark i think. But you are getting what is basically a brand new shell at the end of it.

Hope this helps.

Really that much

Some places use ground up plastic toilet seats! Using this media they are able to strip the paint off in layers without any damage to the panels.

Yeah, I got a quote from a local shot blasting place and they said like 200 quid with priming. But I then spoke to my painter and he said it was only worth doing on the underside etc as it can make it alot harder to paint. I think with CBS you're paying for their time and skill more than anything. They do alot of stuff with mark 1 escorts and their results are spot on. If you wanted you could probably get it blasted in all the non important areas pretty cheaply and then strip the rest by hand. Best thing to do is look up shot blasters in the yellow pages and see what they quote. I found peoples prices vary greatly. I could get you the number of the place near me that quoted 200 but its near Norwich so is miles away from you.

Cheers

Only heard good things about this company.

Was going to buy Micks group a shell.

89xr2

Yeah, there is alot of new medias people are trying out these days. Crushed walnut shells being one of the favourites. As far as I could find out though any paint shop would advise you not to get it all blasted. Unless you want the whole thing skimmed and then sanded back anyway. It would be like watching an episode of american hotrod.

I use both PMS and DMS at work, We use DMS for Steel and PMS for alloy metals and Magnesium alloy

will have to work out cost, but ideally I would like for the whole thing to be blasted as its been 10 different colours in its life. Just imagine the horror under each layer of paint
Thanx guys, keep it coming

JonnyBravo

I've got use of a sandblasting machine to do some work to my nova.

I'm going to do the underside of the car and the inside of the floorpan where there is a small about of rot.

What sort of media should I use ? any ideas where to get some from in the Cambs area ?

I also want to do the inside of the arches so I'm praying for a stronger shell than the escort was

Fez

Sand blasting will remove the paint and rust and metal too.

I'd recommend high pressure (2000-3000bar) water blasting. It will remove paint and dirt but won't hurt the metal.

Mines all ready to be dipped

they quoted me £700

thats to come to my house with a curtain sider lorry load it in there take it to be dipped , then put it in primer after dipping and return it to my house in the back of the lorry so it doesnt get wet

Plastic bead blasting is the best option and the one used on classic cars - it does not damage the panels but gets the shell back to bare metal.

if you buy a copy of classic car etc the comapanies advertise in the back pages

I dont like the sound of chemical stripping as unless the shells are immersed fully afterwards in some kind of cavity wax how can the cavities be properly protected from rusting afterwards

THATS WHATS GOT ME THINKING AT THE MO

by the time you buy a shonky used shell, get it cleaned up, blasted, sealed, repanelled, painted, new glass etc you would have been better off starting with a brand new dry stored one, painted up and ready to go

my mate had a G3 dipped there it was a superb job and saved him loads of time

Damo V

This is true, but apart from wax, all the original zinc coating when first dipped as new will be removed from within the cavities...

Bad News IMO, I know this was discussed a while back and my other concern was the fact acid dipping is usually ysed to remove weight from a body shell, though aparentlty the acid used isnt harsh enough..

If you want it blasted, just get the groves corners seams edges sill etc done, not the panels, there will be hours and hours of filler work to do if the cossie shell has had 10 layers of paint...

Lee Reynolds

Whats in the cavities from new? And you can get to most cavities with waxoyl so surely not a problem!

I like the sound of the dipping rather than blasting! As said, blasting can remove metal too...

plastic bead blasting does not remove metal and does not put a profile to the sheetmetal either like normal shot blasting -at the end of the day acid eats metal as well as everything else it comes into contact with.

As everyone has said its probably a good way to lighten a shell for rallying or racing but cannot see how its long term effects would help a resto project

The guy who restored the e type on the Discovery channel had his shell done with plastic bead - took it back to bright metal and exposed all the corroded steel so that it could be cut out and replaced - shell came back from the blaster like new apart from the rot with no panel damage at all

Tabz @ S.M.Auto's

iTrader: (1)

I see what you mean about the car being dipped, but is this not a cleaner process as they are willing to put a protective primer back onto the metal once stripped, hence no corrosion issues for the future????
Also if they do this I cant see the acid having long enough to work into the metal, as its cleaned away before its ready for primer, so I gather anyway.

jacko

you can allso use crushed wallnut shell as a good blast media witch dosnt harn the steel

Tabz @ S.M.Auto's

iTrader: (1)

Think im swaying towards having it dipped, as many people I have spoken to reckon that its a nightmare trying to clean up all the bead left on the shell.

Lee Reynolds

Something ive never looked into Damo

Lee Reynolds

I remember that! Did all the lead filling too!

TrickyDicky

if you do decide to go the blasting route i have a gun you can borrow and a bucket of sand left(although you will need a compressor as mines bolted down)it makes hell of a mess in your garage though-i'm still finding sand now and i last used it 2 years ago.

Mine cost me £40 to have done as a favour at the local yard



One of the best things I did during the prep stage of the car.

Tricky how about I just pay you to do the job

TrickyDicky

no thanks, last time i tried i got sand in orifices i never knew i had!

my guns only small as well, so would take an age to do complete car, if you find one of these farms that do it they have the proper equipment-somewhere like Tony (NutsRus) took his, they do it every day and quickly!

I'm sure there was a place out Stafford way that did it?
