Thanks in advance for your input.

Silicones are generally pretty hard to stick. The only things that generally stick to them are other silicones.

I've had good results sticking things to silicone rubber with a 1 part silicone mastic (such as you can get from a builder's merchant), in a fairly undemanding application. Silicone foam is just rubber with bubbles in it, so 1 part (ie: acetoxy) silicone should work fine for that too.

There's also a product called silpoxy:


I'm not sure if it will stick to your paint. It may well. You'd just have to try it.

Please let us know how you get on.

HTH & Good luck,

I have always had good luck with aquarium sealer. Just comes in a small tube or larger of course. I always keep this on hand. It seals and adheres to everything I have tried so far including rubber, powder coated and raw metals as well as plastics, which can be difficult to adhere.
