RE: Sealing Engine Bay Area ?
Heck, this is turning into a spitting fight....... sorry if anyone thinks I'm spitting, because I'm just sitting here grinning like the idiot I am.
I wanted to help the beginners. And I asked a question when I should have been dry as dirt and simply stated cold facts.
If you're thinning epoxy with drugstore alcohol, you're thinning it with water as well. How much water depends on the drugstore and how much they put into the alcohol. I have a WALGREENS bottle of 91% that says it is 91% isoproply and the rest is water. If you thin your epoxy with that, you're putting 9% water into the epoxy.
Glues do different things with different additives. Does water evaporate as fast as alcohol? Does the water bond with the epoxy? Does the alcohol bond with the epoxy? Does the water migrate into the wood? Do pigs fly? Who knows any of these answers? <grin>
whatever.........
BTW, I have a guarantee that I apply to my advice. All the guys at my field know it and use it often. If you're not entirely satisfied, there is no additional charge. chuckle.....
