I have a set of chinese bumper reflector LEDs. The front is the red lens and it's glued together with what looks like some sort of clear resin. However, after 1 and half years moisture seems to have made it's way inside the red lens. Even though I applied a thin layer of tiger seal sealant around the edge. So I'm thinking the tiger seal thin layer wasn't strong enough. So now I'm thinking to possibly use some sort of ePoxy. I wanted to put superglue but I've read that it's not water resistant and will break up when exposed to mosture and water. I've used 2 part ePoxy glues in the past which have also come of as a hard thin layer of glue. So question is, does anyone know a glue that I can use (ideally brush on) that can become rock hard and also seal the backing plate to the lens ?
Best glue or ePoxy glue for water seal

Not brush on, but araldite type should work.
Probably as dear as new reflectors though

Something like this? https://www.screwfix.com/p/araldite-2-part-epoxy-adhesive-tubes-opaque-2-x-15ml/2457H
I ended up ordering a new pair as one side has stopped working and the other side has moisture in it. strangely the side with moisture is still working but the side with no moisture inside has died. That's why i'm trying to prevent moisture getting in again on the new pair. Even though i applied thin layer of tiger seal around it, it didn't seem to help, the moisture still got in.

Reflectors either reflect, or they dont. Not quite sure what you mean by not working.
Are we on about different things ?
But yes that type of product

These reflectors are aftermarket chinese ones that have the reflection lens inside but have an outter LED lit like a rectangler border. So the LED part of it has stopped working.

I think you will have your hands full trying to keep wet and/or moisture out of that type of product.
Below is a picture of the unit. The bit that concerned me at first was where the wire enters the unit. The wire seems to be sealed with what looks like hot glue melt which is by no means water-tight. I did put tiger-seal around that originally. Then you have the bit where the lens meets the black rear housing. I originally just applied a thin layer of tiger-seal all the way around the two joints. Now i am thinking to scuff up the surface of both sections and then apply the epoxy.

Honestly I don't think think it is worth the effort, just replace when they die.
But silicone around every possible joint and hole.

I’d agree, you have probably been lucky they have lasted this long.
Hybrid polymer can handle it.
If you buy from china direct (not ebay from china), their stuff lasts forever. I am running china "fly pig" serpentine belts, car badge, engine gasket and rtv, AC refill. All fine for years. Their £1 wipers were crap, but the silicon wiper refills were great.

Being pedantic, CT1 is silicone free.
