Re: Would this measure mantle radioactivity?

If its still functional, it'd detect some radiation from thorium mantles.

Re: VHT flameproof clear

Sometimes, getting the coat thin enough is one of the key points. That would reduce the chances of blistering during heat-cure. This is especially apparent for clear coats that are glossy.

Most of the VHT-type paints that come in rattlecans would require that you thoroughly dry them before attempting to heat-cure.
