Differences in different elastoteric coatings?
Besides a big difference in price what is the difference between Henry's Bright White elastomeric coating and Henry's Tropi-cool, or for that matter Lowes Blackjack white elastomeric roof coating? Why is the Tropic-cool so much more expensive than the others? They are all three white elastomeric coatings. Also how much would it take to cover the top of a 37' skoolie well?
I was also thinking about painting the entire inside with it, prior to applying insulation. Would it do any good, as far as sealing and cooling the bus better?
