You should be sure to chat with folks at Durabak company they're super helpful and nice. They really know what they're talking about too. I was chatting to Joe over durabakcompany.com and even called up mid project for help, real pleased with their customer service.
Fact is this s*** is the best darn stuff out there. I been through them all I should know! Called the folks at durabakcompany.com like 5 times and they were helpful every single time. I only bought a gallon! Hehehe best stuff out there and some of the very best American service I have ever...
