correct. or you can just paint over all the old layers but i'd sand for it to adhere better

 

ya...i tired to paint over but it looks even worse...

what kind of paper should i get?

 

hmmm..... I'd just get the assorted pack of sandpaper. that way you can sand with 800-1000. whatever feels better. i cant think right now

 

Soak the parts in brake fluid. It will remove the paint without hurting the plastic. Depending on the paint it could take up to a week for it to come off. Better slow than damaged.

For sandpaper I recommend using 400 or maybe 600 grit that is water resistant. The paper will last longer and the surface usually comes out smoother when wet sanding.

If you use Fusion paint, you don't have to prime. For any other paint find a good primer and be sure to wet sand before painting for a smooth surface.

 

do i have to remove the paint first before paining again? or can i just sand down to a smooth surface?

 

It depends on your first paint job. If it just looks bad but is well adhered, you can just sand smooth and repaint. If you are unsure or if it's easy to scratch, take it back to bare plastic. Good paint over bad paint equals a short life for your good paint and having to start over. It's better to take the time to do it right now then to have to redo it all over again later.

 

I'd recommend wet sanding whatever you want painted with some 500grit. I've done it before on other cars... It's not that hard. But then again, I was using automotive paint...


If you want to paint something with a texture, and do not want that texture, then of course you'll have to sand off the texture. After sanding off the texture, I'd recommend a prime and guidecoat. It all depends on how you want the final result to be.

But 500grit wet. If I do any parts on my car, that's what I'll do. Just enough of a sand so water won't glide off of and it's not glossy. It'll give the paint a tooth to adhere to.

 

wet sanding means make it wet then sand?

 

yup, sanding while it's wet.

 

i used to have a DIY from when I done mine, it was on another site though...i think its gone now

wet sand with 1000 grit
dip in distilled water bath, wipe down with clean rag
spray 2 coats of plastic adhesion promoter
plastic primer
4 coats of base white
wet sand with 2000 grit
distilled water bath and wipe down
6 coats of pearl white
wet sand with 2000 grit
