So I was at the hardware store and I noticed some 'automotive' as well as 'high temperature' Rustoleum in flat black. I've used the "standard" flat black Rustoleum to "re-finish" an SKS, and that held up pretty well to CLP as well as the heat from firing - though it wasn't quite as durable as I'd have liked (it didn't peel off, but it did scratch off more easily than, say, whatever they put on ARs), so I stripped it.
But what of these other grill/high-temp/automotive Rustoleum products for firearm refinishing? The flat black rustoleum ('consumer grade') goes on pretty evenly and looks like a dark park job. I searched the Internet and I couldn't find any reference to the use of Rustoleum for firearm finishes, which surprised me.
So, has anyone tried Rustoleum refinishing of firearms, particularly the "high temperature" grill variant (1200F rating) or the automotive variant (which, IIRC, suggests a max use temperature of 200F. Would common firing bring a (say) pistol up to 200F? I'd think that a product intended for use in an environment where the culmination of high temperatures (enough to cook food on a grill, at least - at least as hot as a hot gun) and the expected scraping of the object with a metal spatula and metal brush (to remove built-up food) would be able to withstand the common wear and tear a firearm would, yes?
At what temperature is metal able to 'scald' a person? According to this, metal doesn't get to 'faint red' hot until around 930F, and I've never heard of a pistol getting that hot. I know rifle barrels can and do get up past 1500F, though that's kinda at the point that they go "boom".
Can anyone think of a reason why the $5 bottle of 'kick arse' grill/high temp Rustoleum wouldn't be superior to the $8+ "commercial" grade of (say) Krylon/Sherwin Williams, which I hear is essentially Duracoat (or maybe it was Guncoat, I'm not sure)?
So what think you, avid gun people?
BTW: Hi, I'm new!
Stumbled upon this place with a search for "firearm refinishing forum" - this was the first hit.
