I did the "bake" the fog light method of removing the lens... everything was great until the last pull apart. Yeah, I got careless and broke the lower right gasket apart.(not just cracked)

I probably cant get another gasket so can I just fill the broken area gap with some type of silicone and layer it up to complete the seal?? I probably would need to fill both the housing and lens gap to even with the rest of the intact gasket, let it set and then lightly seal when joining the two together before re-installing on car... Am I dreaming my way out of my hasty stupid move?

Anything else I could do/anyone have an extra fog light gasket (Passenger) in good condition????
Thanks! Doug
