You can get some high temp RTV Silicon to add on when you put it back inside the oven for the butyl to soften then push the lens back in then add extra RTV Silicon, or you can buy some Butyl from TRS and order some Switchback LED while you at it.
- regular RTV or high temp RTV? What's the main difference? (just seems like an oxymoron, since "high temp RTV" = high temp Room Temperature Vulcanizing :wink
- silicon or silicone? :smile:
