UPDATE!!!
well got a lil tired of looking at those horrible chrome lights so i grew a HUGE pair and did it. took me a day for the full install...
did the oven at 225 and set them in there for 14 mins
painted them with rust. semi black gloss for plastic
then reheated the oven at 225 for 14 mins to reheat the sealant. and install...
they sealed great and no leaks or nothing. great outcome.
