All I can say is I'm grateful for help.
I posted a link to a YouTube video showing how decals under clear coat can easily be removed from a painted metal fuel tank. I'm wondering if the same procedure could be used to remove the decals on my plastic parts.
Also, someone told me yesterday that if I used a flat paint I would still have to use a satin clear coat to protect the tank parts where my legs touch or else the paint would wear.
I was thinking any type of black would look good - flat, semi-gloss (satin?) or heavy gloss. The wheels are shiny black but many of the plastic pieces on the machine have a flat black color molded in.
My number one goal is to avoid screwing this up. I can purchase new panels that are already colored but dang, that's expen$ive - ouch.
