I do rifles barrels with flex seal spray, its awesome.

Before I started doing this I had called Flexseal to get any melt point info. They told me it was over 250 degrees, I haven’t had a problem yet with moderate or hunting shooting.

I never clean rifles except for the bore and I’m in the elements so much I use my gun as a lightning rod, so this is up my alley.

I just ain’t into the lingering Krylon smell.
