Thanks Dave. Didn't know if one might be easier on the nose or easier to work with. I was kinda figurin' that they were the same because they did the same job but I wanted to hear it from someone that had used them.
 
huge price difference

Current pricing is just under 6x price of Pro-Seal from ACS vs Flamemaster from Van's. Van's quart is $41, ACS pint is $117
