Looking for a little input before painting my 1:1

[Thorsteenster]

I got a 97 Astro conversion van I picked up not long ago, only has 70k miles, 62 at purchase, runs great but looks like poo.
I was going to take a stab at paint rollering after seeing some good results on YT, but then my BIL got a spray gun and gave his 83 CJ7 a reshoot and turned out pretty good.
So we're going to shoot it using Rustoleum Enamel Gloss Smoke Grey, but I'm really wanting more of a matte finish so I'm guessing I'd have to use a matte clear coat?
Also wondering if I should/need to primer the fiberglass high top or body before painting. No rust or anything so thinking just cleaning and sanding would be good.

Any input is appreciated, thanks!

prep is key with any kind of paint job make sure you scuff every inch of that body so the new paint sticks
if the prep is good everything else can be fixed after you spray it with color sanding and more paint
ive done a few rustolium paint jobs in my day they come out ok with the can and the gun ether way a quality automotive clear coat over the top goes a long way

most auto paint stores sell automotive quality paint in spray cans if you dont have a gun to shoot the clesr or just dont feel like cleaning the gun lol

Thanks man, I've got quite a bit of prep to do. The fiberglass high top needs quite a bit of attention prior to painting. Just in the finish, fiberglass itself is fine. I spent a few hours the other weekend with a rubber eraser wheel removing the sweet conversion van stripes.

Can I use body filler as glazing? The high top has some pock marking and glazing compound is pricey so I bought some Bondo filler, a quart for a couple bucks more than a tube of glazing compound.

Speaking of cleaning the gun, I was surprised my BIL bought a gun, not saying he's lazy, but not always the best at cleaning up after lol

be aware bondo shrinks over time and glazing compound is just for tiny scratches its not body filler and from my experiance bondo dosent play nice with fiberglass i use epoxy resin for fiberglass repairs you can use glaxing compound after the fiberglasss has been painted but not on raw fiberglass
