I will keep you updated. The regular version of JB (the best in my opinion) has a psi strenght of 3960 and can take heat to 550.
Its importand to mix 50/50. I did 4 applications, 24 hrs between each. After mixing, I let stand for about 30 minutes, then applied. Its on the road as of Memorial Day. Took three trips, and drove it to work today. Here's the beaut of it. No drips, anywhere now. No coolant, oil, trans fluid, rear end, nothing.
Very pleased so far. I really only wanted to fix 216 temp till 235 is done, howwever, I love it!
