I’ve been using some Loctite Copper RTV on the engine sealing some leaks and I was wondering if I should let it cure before starting the engine?
The instructions say it is tack free in 1 hour and cures to a depth of 6mm in 24 hours, I haven’t put that much on (just a smear) so does anyone know how long I should leave it ?
…and Miles Wilkins doesn?t like Hylomar. He recommends Silicoen RTV instead. QED sold me Hermetite clear silicone sealer for fitment of cam cover halfmoons for example.
I used Hylomar all my life on Land Rover engines and gearboxes and never had any problems though.
My advice is: never use too much (of any) and let it cure fully
