Maybe just being anal retentive, but has anyone used ths Kilz stuff on a project? Want to be sealing foam before spraying it with a black bomb undercoat.
Asking the hive mind.... I've seen the mistakes of now having the foam sealed and having the propellant eating a nearly finished project.

Kilz is white paint. If you buy tinted emulsion/latex paint, it starts out as white, then they add tint to it. So, yes, you can tint Kilz paint. I would recommend applying two coats, to be certain there is no foam left exposed, before black-bombing it.
Also, if you are working with poly-extruded insulation foam, be aware that heating it, even to 170 F, will cause it to melt... Catastrophically! I carved up some sections, applied texturing paper, painted it, then coated it with The Dip, and heated it in a slow cooker pot, to cure the urethane-stain... It melted. Badly shrinking inside of the textured paper, ruining the pieces. While it is made to insulate, it is made to handle temperatures below 120 F, I suspect. It definitely cannot handle temperatures of 170 F, or higher! Cheers!

Yeah the heat gun even in low setting will mess it up if you linger too long.
I was going to tint the kilz with some black acrylic than was thinking "f that". Have some latex around so I'll just give it a thin coat or two of latex, a coat of two of the kilz and black bomb.
Have to try to see some tinting with the kilz as a primer for some of the pigments that give me a hard time... worth experimenting with.

Be careful. Kilz made it's name with alcohol based primer that will eat foam.
Make SURE your paint is latex/acrylic.

Put a few coats on, covered with some liquid latex, and going to prime again before painting. Was my first time using foam on a full scale project. Good thing is even with some of my up close screw ups it will be the cartoonish look that will fit the look of the projects.
