I bought a McMillan fiberglass stock (McSwirley) and have spent the last week filling in pin holes and a few minor imperfections. The stock is 50% olive...25% black and 25% tan and looks nice and has a somewhat nice looking semigloss finish on it from sanding. Would be a really nice finish on a wood stock and that is kind of what it looks like at the moment. Problem is I'm looking for a flat matte finish on this and haven't messed with fiberglass as of the 70s. Don't want the finish just to be setting on top, from what I remember back when is you had to use a HOT finish to I guess burn into the fiberglass and it would stay there. QUESTION: Is there a modern day finish that I can spray from a can and reduce the finish to a nice FLAT, NO SHINE (MATTE) finish or would a professional car painter be the answer to a quality finish. Seems to me back then it had to be what I recall as a "HOT" finish so it would burn into the glass...got any expert fiberglass Corvette or stock painters who would have a detailed answer for me! Thanks in advance.

This is the fiberglass stock I am referring to.

You can paint it with anything; for best durability use a two part epoxy type, or automotive paint with hardener, but anything will stick as long as the surface is clean. I have painted a few composite stocks with the same paint I use on WW2 Jeeps; flat OD, code 33070. Works fine.

Sorry, I repeated myself to many times.
Question is: It is too glossy but I like the marbled coloring that it is now...
Can I spray a flat base Polly on fiberglass and have it hold up and knock the shine off of it.
I do NOT want to spray paint it a different color.

I think that would work fine.

Steve try this stuff. It will do what you are trying to accomplish.

Helmsman spar urethane; I have used a lot of it and it is good stuff.

Rub it down with Scotchbrite or steel wool....please don't spray it

I would try this first. If it doesn't work you still have the option to spray it.

There is an amateur radio antenna maker who recommends their fiberglass antenna parts be coated . That's to protect the resin from UV. Are there any problems like that for stocks ? They aren't always exposed to the elements like antennas.

Thanks for the responses, was out of pocket a couple days.
LesBrooks, you win...I'm going to give that a try on a small section first and see if it's what I'm after. I think it will be.
