Cheers Doug..L8

5 x ready to be painted 17 x 8 OZ mag superlites No pics until done but same as my sig wheels but bigger

Question 1......can i paint these with aerosol..i know you cant powder coat magnesium...so will it be ok????

Question 2......on each flat bit where the stickers go there are 4 tiny threaded holes,what they for?

 

Question 1: No idea


Question 2: Little holes like these are to bolt on brake cooling discs

 

yeah, sure they are for cooling ducts

b9kos how many sets of wheels you got now?

 

Only three now Sold the old skool comps, but may be getting them back

The 17inch OZ mags in the pic above were borrowed from a friend so i could see what my Ripleys would look like

 

I had my magnesium wheels powder coated......

 

think it depends on how much magnessium there is in the wheel

dont think i would powder coat them oz's

 

I had my old mag rims painted in a std bodyshop with "normal" paint

 

the wheel you see in the pic on rich car is powdercoated as are the other 5 that the owner of the wheel has, with no problems.

 

Aerosol paint will be fine as long as its got a good key.

 

areosol would look shit imo ,.

why not get the blasted with a mild meida , or walnut shells or summit and 2 k paint them ,

fuck knows u got the money ?

 

I was told its fine to powercoat but they have to be baked for a long (couple of days) period to get the air out. Had my my centres done and no problems.

we powder coat all our mag wheels, weather rd going wheels or racing wheels

 

I gave my CSL rims in to be powder coated today - dont they have magnesium in them?

I'm sure they'll be ok

 

Beefy

why would they look shit? when i done craig todds old wheels which were the same as phils i done them with aerosol and they looked spot on

heres a pic

 

yeah but ive seen craigs and they look shit ,

probably the shonky workmanship of the painter

just thinking if hes going to be blatting about the roads and track , 2k may stand up better ,

i mean craigs aint a comparision , it gets driven evrywere at tem miles an hour and he only has it out three times a year

how u doing fella

 

phil on a track come on beef

 

you can powder coat mag, its down the the cleaning process first, also genrally helps if you use an alkaline chromate process such as Alochrome which prevents most of the porosity problrms caused by mag castings

 

...so do i primer then paint then laquer..or just use a good wheel spray?......fuck paying big money ...its a rally car

 

Just prime and paint them, don't rub them down if possible and take any of the protective coating off as Mag wheels have a anodised like coating from factory.

 

on second thoughts

areosol will do just fine phil !

 

Phil, if they in decent nick then a paint/bodyshop wont charge much to do them in 2k mate.

 

2K gets my vote as well, aersol is such a piss weak mix of paint its just not really any good, it will look ok initially but wont last.

 

 

..they are bead blasted ready....i thought when i saw 2k thats how much i should spend on painting them

...incidentally as they are all bead blasted can you just paint the face or does where the tyre fits need doin aswell and backs?...

 

BTTT

 

Depends on what aerosol but it can be fine!!

 

18's are no good on a sapphire,17's much better.

 

Normal rattle can should last, all down to prep etc.
If you take your time, and have a decent surface for it to go onto etc.
I used a good amount of primer, pigment, then lacquer.
Once the lacquer is polished back, and you get and keep a layer or two of good
wheel sealant, should look like new for as long as you look after them, and keep them cleaned/sealed.
Keep them sealed and there's no need for aggressive or acidic cleaning methods,
simply shampoo will do.

This is rattle can finished
Gleaming in the sun after months of use

Halfords can aren't particularly good, unsure of a decent paint for the colour you require, but for lacquer Wurth is very good

 

I wouldnt do the backs on the lip/rim Phil, I had a small amount of paint on myu Old Style MO's and it affected the seal of the bead on the tyre and 1 out of the 4 wheels kept leaking air quite quickly, having now cleaned it off they are all fine!

 

I 'think' that mag corrodes from the inside if not protected, the first you will know is when it brakes Therfore I would paint / coat / protect all surfaces i.e. inside the tyre and beads to, better safe than sorry and all that shit

 

magnessium much like Aluminium forms a rapidly oxidiseing layer which in turn can lead to degredation of the material, on Aircraft applications there are strict proceedures about treating after blasting to prevent this, another problem associated with Magnessium alloys is that it age hardens much quicker than alot of alloys meaning it becomes quite brittle and much reduces its servicable life
