Can anyone advise me on the best way of doing the underside of my car . Im going to take everything off and get suspension componenents blasted and powdercoated or new where needed. Fit new bushes throughout and finally get rid of the ABS and old brakes lines.

Whats the best way of getting the old underseal etc off , and what do i do then to the underside?

Any help appreciated

 

I have seen people use wire brush attachment on a grinder/drill to remove the old underseal then once the underside is clean enough re stone chipped then painted.

In 3 weeks a mate of mine is bringing his S2 to the guy who sorts mine for a full spray under and over I'll get pics of the job and post them for you.

 

Smashin , i just need to get all the info before i do it .

Want to get it looking mint

Best way i found to get old underseal off was with heat gun and a scraper of some sort. Check mine out in resto section

 

I turned mine over onto its side to strip it off but if you cant do that get the car as high as you possibly can safely then heat it up abit then use a paint scraper of sum sort it will take some time so you'll have to be patiant when your doing it.
Have a look at my resto thread if you want to see how i done mine

 

them scotch brite thingys that go on the grinder are supposed to be pretty good

 

they are mate ,use them on a drill aswell

 

Thats what i meant

 

Much much much patience and hard hard work.
It is totally soul destroying.
that said!
the very best tool for you is a mbx wheel not cheap but good.
or wurth do a wheel that fis a grinder which is far courser than a "wire brush" and retails for about 20 quid.
Beware though press too hard on soft metal and it will burn through.
You dont necessarily need to take everything off just create a good key for what you are putting over it, You must however make sure you thoroughly degrease prior to recoating as no paint ever likes grease and of course depending on the look you are going for replace the seam sealer then topcoat.

If you do it properly you could end up with something like this.

We used a far more durable coating under the arches as series 1 turbo doesn't have archliners. for that we used the 3m spray sealer which is around £10 a bag.
For the underneath we used the upol stuff (gravi tex i think) as we wanted a less stippled finish. you apply it with your bog standard shutz gun, that is asssuming you have access to air facilities.
Believe me if you dont have air tools its alot harder...

 

My rst underside was steam cleaned, cost about 35£.

September same shop will wash it again and take the exhaust off and spray epox paint.
Next winter i rip off the suspension etc and sandblast them and paint and new bushes.
