Never coat directly over old paint in poor condition, cracking or peeling paint or clear coat without addressing the situation correctly.
If you know or suspect that there was rattle can paint used on surfaces from a previous owner, STOP, ask questions, check to be sure what you are dealing with (See section…. )
Never install ML over bare steel or aluminum without proper surface prep and correct primer. See Section XX.XX
Never install ML over existing rust without proper treatment or rust removal and correct primer. See Section XX.XX
Leaving can open
Direct sun
Hot surfaces
Always and Nevers
Applying too much pressure may ruin the brush or leave roller marks.
Do not try to squeeze every last drop of paint out of the roller before rewetting
Always Do your disassembly and prep on a different day than the coating installation
Never work from an open can of Monstaliner
If you need to buy a roller pan, get only a narrow one as the full size pans for 9” rollers leaves too much surface area exposed to the air.
Always apply 1st coat thin and conserve material for 2nd coat
Always scrape down inside walls of can after 1st coat.
Always do the “Solvent Float” in the liner can between coats
NEVER USE LACQUER THINNER OR ALCOHOLS ON SURFACES TO BE COATED
Outside HOT
You want to avoid direct sun and hot surfaces that sat in the sun before starting to coat. I assume you will be working outside. If you had some overhead cover like a tent or carport type structure it would help and you could maybe pick a less humid day. I have rolled this stuff in 100 degrees and the only real caution would be to never leave the can sitting open for more time than it takes to pour more material into a roller pan. Your 1st coat will dry faster to recoat but that’s only better to finish faster. I would go for it. Also, at the end of the first coat make sure to float a few ounces of MEK, Acetone or xylene over the surface of remaining coating in the can, then close lid tight. This will prevent skinning and the possibility of mixing chunks into the coating at start of 2nd coat. Just mix in the floating solvent when you start 2nd coat. You could also add a few oz of solvent at any time if you think the stuff is getting too thick.
