Etch primer

Etch primer
Hi all
I am going to be repainting my wheels in a couple of weeks time as they are getting quite corroded and look pretty scabby. I will be blasting out all the corrosion but probably leave the good paint on the wheels as it will take a lot of time to blast it all off.
Should I use etch primer first, or will ordinary primer be ok? Will etch primer be safe to use on top of old paint?
Thanks
Rich

They're the standard wheels off my st170. Just using a rattle can, i have done wheels this way before and they have come out alright. I know i'm not gonna get an excellent finish but its just to last another year or so until i will be replacing them!

remove all the flaky bits of paint, feather the "sharp" edges of paint back with 240 grit. Key the full surface to be primed then fire away as said above

From experience (painting cars too long basically) you'll need etch primer. Chromate etch primer helps adhesion of your 2k primer.
Try avoid etch from an aerosol can. When its applied from a spray gun its evenly applied and i feel you can get the product into the tight edges easier.
2 or 3 coats of 2k acrylic primer over your etch then you should be on the road to recovery
Quick tip; If your priming the wheels yourself dont force dry the etch primer (with a heat gun of by blowing air from the spray gun) it forms a skin on the top of the etch while its still wet underneath. If the 2k is sprayed over it then there is a big possibility your paint could peel off down the line. So leave it naturally dry
Hope this helps

Agree with the above if it want it to last then it will need at least a coat of etch, if its only a few small areas that are busted thru to bare ally thou mate u might find it cheaper to buy it in a can than gettting it in a tin and the thinner for it etc.
If the ally is in good condition and is prepped properly you can actually go wet on wet with etch ie get it all ready then dust a couple coats on then go straight on with a colour after its flashed, but by the sound of it u will need a couple coats of high build on it aswell!!

Thanks all for your replies and advice! We do have painters at work who could do them for me, but as i said i only really want a quick job done on them to tidy them up as cheap as poss as I will be replacing them soon anyway.
I'll go find myself some etch primer
Cheers!
