TY250A Seat Base Questions

[mr neutron]

Hey, All!

I'm slowly getting work done on my project TY250A. I got the swingarm "repaired", sandblasted, primered and shot some rattle can enamel on it today. The old "bumps" on the the swingarm that the snail chain adjusters push off of were really worn with grooves somehow. Maybe someone (previous owner) let the rear axle get loose? I say this because there is also damage to the dust collar on the drive side of the sprocket and the inside of the swingarm itself. I dunno how it could've happened, but it did. I ground off the old bumps, and drilled and tapped for 6mm allen headed bolts for the adjusters to work from:

 

Now, I'm working on my fiberglass seat base. I made new brackets for the seat's rear mount before I found out that Feked sells them.  Now, I'm sanding off the yellow flaking paint the PO put on, as well as some of the original yellow, down to the bare 'glass. My questions are:

Does painting fiberglass actually require any "special" type of primer and paint? I'd really like to just put on some paint I can easily/inexpensively buy for now, and can use for future repairs. Something like a rattle can primer with rattle can hi-gloss enamel over that? I don't really want to shoot, say, colored gel coat on, or some of the more pricey marine products. Sorry for what's probably a stupid question. I suppose I need to say that I want this bike to be something I ride and crash, not a restoration showpiece. It's been 40+ years since I've done any bodywork involving fiberglass, and while I don't recall doing anything special while putting on and glassing in some fiberglass fender flares for my old Datsun 510, I would suppose there's been some improvements in chemicals for painting fiberglass by now........

Thanks for your help here,
