spraying plastic

[JonnyM]

hi people,
just attempted to spray a grillie i found on a clio in a scrapyard thats the same as the valver grill, so i sanded it down with 1200, made sure it was clean ect ect but when iv come to spray it the paint has kinda gone blotchy like it has something on the surface so iv ended up with lots of bits were the paint has almost run off leaving lots of unpainted grille if that makes sense, its odd because its not run but it wont cover the certain areas, any ideas on how i can remidly this?
cheers

Sand it down , degrease it first with some panel wipe and maybe use a tack cloth to clean off any powder from sanding , then use plastic primer first before the top coat .

^ what he said, but it will probs peel and chip over time.

if you use notromors on plastic will you be able to repaint over it or will the plastic possibly 'soak' a bit up?

no chance!!!

sand it flat again, plastic primer it, then paint it, then clear

Yep.

Sand, clean, primer (3-4 coats), paint (3-4 coats), lacquer (3-4 coats).

Spray it lightly and don't go over the same place twice on each coat. You maybe are holding the can too close.

oh and degrease it before you spray it otherwise the paint won't stick

1200 is probably a bit fine at first. You want 800, pre paint, plastic primer, pre paint, base, clear. Then if you have runs in the laquer or orange peel. Wet flat with 1500+ and then polish it up with megs scratch x or similar.
