Thanks, so far I can't see the cracks that were repaired (I used a stone to smooth it over). Now I am not an expert but this seems like a pretty serious product. Nothing will get it off my hands, no amount of scrubbing, hand cleaner thinner or even Methol Ethol Keytone MEK. I tried to use latex gloves but they stuck, becme soft and tore quickly. I put on rubber gloves but small amounts were on everything I worked with so I am wearing some of it.
I covered the first two bays completely and was into the second on just the first 5 gallon container alone. I still have 7.5 gallons left
My friend was the one who helped me aquire the product, he does this for a living but unforetunetly he lives 2 states away. I called him with any and all questions I had before doing anything. He said there was no need to scrub the acid in during etching, no need to wait 3 minutes, he said it would fiz and turn green quickly. He was correct. I am very happy so far.
