In theory couldn`t you also get double the protection and double the durability by adding a 2nd coat of sealant? If something is going to strip the sealant, then it`s going to strip the sealant, regardless of what it is bonded to. So, if the PBA has better bonding and durability, why not just use that as a LSP? Just playing devil`s advocate.
It is an interesting question and I would love to see a side by side comparison on a hood and a door (to test against winter conditions). One test with just the elements, and one with a wash of a concentration that is just strong enough to compromise the sealant. (Like CGCW) I`m thinking 3 sections. One coat sealant, two coats sealant, & PBA with one coat sealant. If the PBA section cannot hold up better than 2 coats I see no point. Anyone looking for durability as the primary factor should be looking at a coating rather than a sealant.
I will be very interested in reading your results, Bobby.
