Re: Paint products for firearms.
On my rig I used a product called LIC43, made by a company called Valspar, I think it is marketed under LIC brand, it'S made in the USA
The LIC43 is the "Matt" of the range.
It is a 2 Pak and is hard as hell, like really hard.
Impervious to every cleaning solution I own, it requires very little prep, and goes on really well.
If your barrel is a blast finish just a good degrease and spray it, smooth give it a good going over with 280 grit, degrease until clean cloths comes away clean, spray it
The trick with it to get a good Matt finish,is more air than paint on the spray gun. light coats too, if you get it right it will "matt off" almost immediatly, get it wrong and it will become a semi gloss look(put on too thick). it still looks ok,but once its on "its on there!"one even coat is enough.
Ive sprayed 3 guns with this stuff and its brilliant,my one is in "gun photos, Barnard 338LM"
