Modern Buddy

Background:
I purchased a 2007 Buddy 125 Italia for my wife last week, and am in the process of repainting the faded interior parts. I went with Rustoleum Painter's Touch x2 as it has received great reviews when used on plastic. We sanded and cleaned all parts prior to spraying. No primer was used as many claim this paint sticks well on plastic, and reacts badly with primer.

Question:
How many coats of paint would you recommend? I presently have 3 coats of flat black on the scoot, and the parts look as black as batman's suit. Will adding more paint increase durability? Should I use a matte clear coat to increase durability? I'm always hesitant to use a rattle can clear coat as I've had it react badly with the underlying paint before.

Try the matte clear coat on a piece of scrap. Put a few coats of the black on some junk plastic of similar construction then let it cure, then try the clearcoat. I will immagine the flat black will scuff bad without the clearcoat.

I used some of the painters touch matte clearcoat on some computer parts recently and it looked ok, but it's not going to be in the weather or possibly scuffed up. Best of luck to you!

I used that same paint last weekend to paint a ladder ball set and with 1 coat it's great (covers well too) but in some places with 2 coats, where it got a little thick, it crazed the undercoat and looks like shit. Could be because it’s xylene based and it didn’t like the PVC, IDK.
Otherwise colors look great and sheen is nice too.

It sounds like I should add a few coats of matte clear coat then. Will i need to wetsand before adding the matte clear, or can I just spray it on top?

I wetsand with 2000 grit myself, but do what you like. Can't hurt to sand.
