I need to coat my old M1A scout hand guard to match a stock I am installing. All I need to repaint is the slotted hand guard and I hate to spend the $40 for Duracoat spray and have all that wasted excess for such a small project if something else will work reasonably well. Is there an paint alternative I can easily find available that will do the job and hold up to regular use and the heat of the barrel? I have heard others mention just to use Krylon and that it holds up really good in such areas.
