What is the "Tight Seal" stuff made of? Sounds as though it is very resistant to heat and oil based fluids. When you were sealing between two surfaces did you use the tight seal by itself, or in conjunction with a gasket?
If you used the tight seal in conjunction with a gasket did you coat both sides of the gasket prior to pressing the mating surfaces together? I always like to learn about new stuff that is not standard materials that you find in the conventional hot rodding world. Especially if the product prevents fluid
leaks. Oh how I hate to detail the bottom side of my '32 and then have ten drops of oil explode all over everthing it touches while I am cruising and the bottom side of my ride end up looking like I ran over a case of 10W30 at 60MPH.
