Just did this yesterday, what a PITA. The baking was easy, it's the disassembly and re-assembly of the headlight that takes the longest. So many torx screws that I had to be really organized and remember where everything went!
As far as re-sealing I said the hell with silicone and just re-heated the OEM adhesive. Pics to follow
