Attn Paint Gurus: Can I paint over powder coat?

[Fireball05]

Hello all -

Here's the quick question: can I paint overtop of powdercoat? Any special prep work needed or just scuff and shoot?

Long story short: I just had my wheels blasted, cleaned, prepped and 2 coats of powder coat. Gave them the Wimbledon White PC color found on here. They couldn't find anyone to sell them less than 55# of the PPG powder, they called Tagger and got an equivalent code RAL9010 they were told would match. They did an awesome job with the PC work, however, the color is not correct. So I now need to have them painted.

The PC guy said that they can be painted over, no problems. Looking for the advice of some painters though.

Thanks!

yes you can paint over powdercoat,just prep the same as you would paint over paint,,220 grit or 320 grit is fine

Thanks for the quick response. Some generic Internet searching revealed the same answer so I'll give it a go. Since its brand new powder I was going to skip the primer. Is that a bad idea?

Thanks !

id scuff with 320, then a red scotchbrite pad, then wipe down with prep-all then shoot a coat of sealer then 2 coats of single stage or do base/clear. I think you can skip primer but the sealer is needed.

That is the quickest and the way I would do it. If you decide to prime it's not wrong to but more steps involved. If you prime sand with 220-320 then apply primer. Wait to dry then sand with 400 or finer and a red scuff pad then paint. With sealer you apply it, wait for it to flash off then apply paint. No sanding needed and is faster and easier.
You can't paint solvent paint overtop of anything coarser than 400 unless you seal it. Sealer you can't go any coarser than 320. If you do you will see sand scratches either right away or later down the road.
