Thanks guys, I think I'll go ahead and use the TBIII, I havent done one of these in quite a few years so this one just to get back in the groove, I'll get some URAC when I get enough material together to do a couple of these.
Can someone run through the process of how they apply the TBIII and what is the approx working time you have with it, I'm in about 80 degree high humidity weather now. Thanks, Craig
