Hey everybody,
So I'm gonna paint my stock cherokee rims black to match my black and grey theme I got going on an was wondering what a good spray for metal would be? I have some left over krylon fusion from my trim and its says it adheres to metal well but was just curious I there was something btetter?
Thanks

 

...99% of spray paint adheres to metal...

 

So any old one would work good? Maybe one for plastics is the 1%?

 

Krylon Fusion sticks to metal also.

I can't think of a spray paint that's not meant for metal.

Except for chrome. It's meant for Bok Cheby's.

 

Just make sure you prep the surface properly. You'll need to sand it with a fine grit sandpaper in order for the paint to stick properly.

 

Really? An automotive painter in my class said to hit it with some 100 or 150... Which I've done slowly when I have the time, all but one wheel is already sanded

 

Use primer. Rough the metal up. Apply primer. Rough the primer. Repeat until it's smooth as ****. Apply paint.

 

This is the true right way to do it but it sounds like you're looking to do this quick and cheap that's why I only said sand with fine grit to allow the paint to stick. It all depends on what was on the wheels before (just bare metal, painted, powder coated, etc.)

100% proper way would be sand down to bare metal, smooth the surface, primer, sand, rinse/repeat a few times, paint, wet sand, paint, wet sand clear coat, wet sand. I don't work at a body shop though so there might be better instructions/advice out there lol.

 

I used a wire wheel on my drill along with some sandpaper (180 then 220) to scuff up the surface. Followed up with a self etching primer, then flat black rustoleum. Turned out pretty good, and touch up is quick and easy.

Yea looks good, I got the rustoleum but whats this self etching primer?

That is the stuff I used on my bumpers etc. Works Great!

 

The self etching primer just uses another chemical in it (zinc chromate?) to etch the metal (give it a profile) so the paint will adhere a little better.

I believe that is correct at least, it's been a while since I dealt with this.

"If you ask the manufacturer like I did you can get the correct answer.

Self etch primer is for metal that has not been etched by some other means. So if you are building a something and weld up some brand new sheets of the steel and do not want to sand them you use the self etch primer. The job of self etch primer is to make a good surface for putting the next layer of paint on to the metal. If the metal is already a good surface for a direct to metal paint then you do not need (and do not want) an etching primer.

The etch primer has been improperly thought of as a way to prevent corrosion. I had the local dupont paint store guy try to sell it to me for that purpose.

For most of what we are doing the better solution is to etch the metal. Either with various chemical methods such as Pickle X or metal pre-treats the paint companies sell. We can also sand the metal or even better sandblast. Then put down a nice layer of epoxy to seal the metal from moisture.

Of course do not forget to use a proper wax/ grease remover before painting."


Basically it allows smooth metal, (good for the oh so hated galvanized metal) to take a good primer coat that will allow the top coats to adhere right. in my experience, using self etching primer on bare unsanded metal, makes the top layers much less likely to flake off.

 

Good to know... thanks for the clarification!

 

Sand, self etching primer, paint, clear coat. Spend the extra dollar or two on wheel paint and wheel primer and they'll last a lot longer. Just about every auto store sells it.

If you've got a local truck wash it's not a bad idea to hit them with the engine/tire degreaser at one after you sand them then scrub them with some dish soap and water. Definitely want to make sure grease and such is gone.
