There was supposed to be enough to coat two five gallon tanks so I figured to be safe with doing four of the five tanks for a cost of $15 each. This was a two part epoxy mixture. Very economical compared to places that specialize in this process. CASWELL instructions describe "swilling" the mixture around in the tank to get an even coating. When I open the containers, the liquid was like molasses! (swill it???) Epoxies generate heat when mixed in larger quantities and become very liquid, so assuming this was what would happen I preceeded to mix the two liquids......no heat generated and it remained thick. Still stirring, I placed my container on the forced air heat vent to warm it up and hopefully become thinner......no luck. I plugged in my hot plate and stirred it on there. Here I was worried about a "flash point" and causing premature hardening. Still no thinner but I had to get it in the tanks. I poured 1/4 of the mixture in each of four tanks and slowly rotated the tanks for the "molasses mixture" to flow over the interior surfaces. There was no swilling, not even close but the mixture did flow and coat the inside (by what I could see through the filler neck). The rustiest tank I had, let the mixture flow out through a couple pin holes which I had not seen ( this was good). I left the tanks for several days and found that the coating had dried hard and clear like glass. All tanks have been holding gas without leaking but could not do this before the application of the sealer. Most of them were leaking around the end seams. Despite my worrysome experience with this "molasses" mixture, it seems to have done the job. I plan to contact CASWELL about my experience and will update here on this forum.
