Will Hydro Seal bond to itself? In other words, can you layer Hydro Seal?
yes
from what I understand it just doesnt like to lay down without streaks when you wash first with a polymer enhanced carwash soap. Polymers in soaps are dispersed very loosely and are different than the way they tightly setup with a purpose built sealant or sythetic wax that cures. so that would be the only issue with application.
btw, i tested it out on a panel and felt that using water was a better option than using hydro spray wax as a spritz. with the water I just felt that the product had a better feel to it, and applied more evenly and you could feel where it clearly went on. with the hydro wax, it kind of confuses the feeling of whether your applying it correctly or not.
nick, am i off base with any of these statements ?
