Permatex Flowable Silicone + coolant seals

Any1 have experience using this product to enhance sealing of the water seals?
https://www.permatex.com/products/ad...-glass-sealer/

Thinking of applying on the rotor housing contact surface to help both compression and coolant stay where they belong.
Being more fluid, I'm assuming it gives more time than regular RTV to set during assembly.

Consequences?

its really thin, soupy, and a skin coat would work well (does work well in fact)

Honestly if the surfaces are clean and the coolant seal walls aren't compromised I've never seen a problem with coolant seals. Unless of course you consistently run too hot, hell on the e-prod engines I build (20 hours max) I superglue the outer coolant seals and reuse them.

25+year old engine so seal walls not perfect and valley have some minor pitting on a couple of areas.. And bead blasting of rotor housing leaves a surface not perfectly smooth as in new. Addition of RTV comforts me that both compression and coolant will unlikely work their way across.

You do you, mang. I'm located in Mariah's old building up in Santa Barbara if you'd like to come by/are curious about other build gear/engine parts.

Fuggit, just use Right Stuff urethane on everything.


My water jackets are corroded through to the water seal grooves in many spots. No problem.
