Can you spray over powdercoat?
I want to spray the rollcage of the Ultima cockpit Orange, so do I need to strip the powdercoat? or can I spray straight over it?!

Anybody got any experience?!

You'd almost certainly need to key (sand) it a bit with something like a 240 grit wet and dry for starters, and then primer it; don't think you'd need to take it all the way back thouugh.

Although having said that, I did touch up a few bits on my Aeon by directly painting on it (in the same colour - but a bit has begun to peel off).

Powder coat makes an excellent base for new paint.....so long as you key it properly.
You'll find it quite tough to rub down so you may need to be a bit more aggressive than you would with a painted surface.
Just done some wheels,changed the colour from powder coat silver to 2k black no problems at all.

I'd be tempted to give it a light to medium rub-down with some thinners - although this would soften the powder coating, so I'm not 100% sure about that.

Then, 180 to 240 grit wet and dry.

As to primer - I'd try a plastic compatible primer. Then it's normal painting.

Note: while I've painted 2 of my cars, I wouldn't qualify myself as any kind of expert though!

I'm assuming you'll be using 2K here,if not this may not apply but I'd give it a good flat with 240's,dry,followed by red scotch and then you're ready for topcoat,you don't need primer unless you break thru' the powdercoat
