I am doing the do-it-yourself paintjob and have a few questions.
I am using Rust-O-Leam Camoflage paints and Helmsman Spar-Urethane. Painting the upper, lower, FF HG, M4 stock, & FSB.
For the curing, can I bake the rifle in the oven, and at what temperature? I am using Colt 4-pos stock and TDI/CAA cheekweld & standard A2 grip for the plastic parts.
Just lay it on the rack, or on top of tin'foil, cookie sheet or?
If I can bake it for curing, should it be before or after Spar-urethane is applied?
I'm thinking 5-7 coats of Spar-urethane, too much, too little?
How will this finish hold up? I have read it is pretty durable, anyone with experience?
Any suggestions for increasing durability?
I'm painting 2 mags also, I'm removing the follower and spring, can I leave on the Magpul Ranger plate? Leave it on the oven?
Do you need to bake those paints for curing?
I just use Krylon Matte (though I'm going to try Norrells soon) and you don't need to bake the Krylon.
5 or more coats sounds excessive to me. I just apply a base color, then add additional colors on top in the pattern I desire. Maybe we have different goals.
I believe the plastic will hold up for limited time at 200-250 F. I'm not sure though, so don't rely on that. More knowledgable people will be around shortly I'm sure.
There was a very good post several months ago that explained the krylon process very well, it is somewhere in the archive and the link I have does not work. However, Bulldog Arms makes stencil kits for various cammo patterns and has good instructions on how to apply the paint and their stencils here
+1 for that being a lot of work to use krylon
i used the urethane stuff and it just made everything sticky, especially the plastic parts.
imo if you plan on going through all that trouble go with something else. with krylon i just layed the gun out and sprayed it, afterwards i hit it with the heat gun to speed the drying process and that was it.
