painting a scooter
hey guys im new here and i have a question about painting plastic (it might be fiberglass(?))

anyway i bought a scooter earlier this summer and decided that i want to go ahead and paint it. i stripped the plastics off and sanded the glossy finish down and im left with this

i then go out to home depot and buy some automotive primer in a spray can thinking that automotive primer would stick to it

i did a test patch on one of the pieces and im now stuck with this

the one coat of primer scratches right off under my fingernail as shown ^^^

what type of paint should i be using on this?

I think with Fiberglass you want to use an epoxy based primer but something is up if your automotive primer is just scraping off that easy. Exactly what brand primer is it ?

rustoleum auto primer

can i please have some more info on the epoxy based primer? would i be able to spray paint on top of it?

What did you use to wipe it down after you sanded? Also, what grit sand paper did you finish with?

perhaps it has wax on it?

i used a wall sander kind of thing for the bulk of it along with sand paper which i have no idea what grit it was to finish+get to the hard to reach stuff

Sand the primer off. Go over the entire thing with a scotch-brite pad (maroon/general purpose). Blow off the dust with compressed air or wash it down with soap and water. Dry it. Put latex gloves on and wipe the entire thing down with a grease/wax remover and then wipe it down with a tack cloth. Then you'll be ready to paint.

can you afford to take it to an autobody place that sandblasts? if it EVER was waxed, you'll have these exact problems with ANY paint you try to put on it.

If the material you're trying to paint IS fiberglass, I'd be inclined to phone up any auto body shop and ask if they use a different primer when repairing and repainting Corvettes. My understanding is that the body of Corvettes are made of fiberglass, not steel.

Also, any marina would know who to refer you to who repairs fiberglass boats (and canoes). Someone familiar with repairing fiberglass would know if you need to use a special primer on it.

If that primer comes off just by scratching it, you might be able to remove the primer fast 'n easy by sticking duct tape to it, and then pulling the duct tape off. Or, any really tacky tape, like packaging tape, which is far cheaper than duct tape.
