That's true, but that's assuming that the drum never gets over regular smoking temps. Actually, there's no need for paint at all, really.
But let's just say you did want to paint it and, hypothetically speaking of course
, that the drum accidentally goes above, say 400° (or higher) on the side therm.
Of course this would never
, but if it did
, like say someone didn't make sure they put the lid back on properly after they took the tri tips off, the hi temp is not bad insurance.
Oddly specific example, huh.
The Duplicolor stuff isn't bad price wise. I think I paid like $6 a can. I think I used 2 cans of primer and 3 cans of yellow. And it comes in such pretty colors.
