Assembly Lube
Used this on all moving parts for a total engine overhaul which included a reman crankshaft installation for 1999 Chevy 4.3L vortec v6 - Vin"W" engine. Nice red color show where applied! Tacky assembly lube! Pretty much stays put! Seems to mix with engine oil with great ease over the initial start up of engine. More than enough lube in this bottle to do 2 engine rebuilds... didn't even use 1/2 bottle for my project, and I really laid it on there thick! Nice product!

Decent Product
Good Assembly Lube, but I also Purchased Lucas Assembly Lube From Autozone and The Lucas Was Alot more Tacky, for sticking to the parts better, but we used this permatex to install the ValveTrain and it made things slid in very easy

Is this suitable to coat pistons and cylinders with ?
Verified Reply - John the Car-Doc
Hi Alan, I'm glad to assist you! Permatex only recommends this Ultra Slick Engine Assembly Lubricant - Part # 81950 for engine bearings, camshafts, lifters, valves, guides, and rocker shaft assemblies. However, it should work, just put a thin film on the piston and cylinder, and don't overdo it. Also, I'd recommend that you contact Permatex directly at 1-877-376-2839 and one of their Parts Pros will gladly assist you with this question.
Is this acceptable to use in automatic transmissions?

For more information, I would suggest that you contact the manufacturer directly at https://www.permatex.com/contact/ and they would be in a better position to help you.
Would this be good for fuel injector replacement?
