Thanks Kipnlilo. I already ordered and received the Polygem 1319. I'm pretty confident that it be OK. Depending on the results, if I need more clear coat, I may consider the Pond Armor if things don't go well. If my tests go well, and I use all of it up, I might get their better product though. I'll post results. At least everyone will know if there is another product out there that will do the job or not in case Pond Armor goes out of business or something. If the tests fail, then I'll purchase the Pond Armor. Thanks for the recommendation everyone.
