Hi Guy's I have some submersible lights for my boat trailer (my second set) anyway these I didn't crack when I tightened the 6 screws to the clear so called water tight cover.

Thing is just like the 7 year old set the plastic cover has already cracked just by road vibration I suspect (only one use)

Anyway what I am wanting is a flexible non setting sealer I could use to help the rubber ring keep the water out. I have tried Vaseline but thats a bit thin need something a bit thicker.

Any ideas?

Thanks Justin.

When replacing the overcab window in our campervan the glazier advised sealing it with Selly's No More Gaps, as it would seal and not glue the window in permanently.

I've used selleys wet seal with success on a variety of things that it wasn't designed for. While it does go "off" it stays very rubbery and can be separated down the track. It will eventually reach the stage after a few years that it will need a bit of persuasion with a stanley knife or similar but still comes off.
It can also be painted unlike silicone.

The clue is to use a silicone sealant but wipe a film of oil or grease over one face before applying the sealant to the other face. Then join the two parts normally. The oily face prevents the sealant from sticking and can be easily disassembled.

This technique also works with No More Gaps.

Paintable silicone sealant is readily available if needed.

Thanks Ozhumvee, I might go down that route yet.

Not a bad idea there Allan, pretty obvious so why didn't I think of it, and the Vas is already smeared on there.

Mate,
spend the coin and get LED's, once mounted they never need maintenence, 100% waterproof, just don't cut the cable too close to the light, join the wires as far away from the rear as possible.

Thanks Shane the jury is still out for me on LED's for the boat trailer apart from some leds I hear are still burning out before there time there is still wicking of the internal wiring. And worse theft at boat ramps.

But I will get them eventually when the price comes down and everyone has them, Cheers.

Lanolin Grease is one of the most waterproof greases around and it won't affect plastics the way petrochemicals do.

Sheep spent centuries developing it.
