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,

Leo

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.
