I'm looking to get some tips from the experienced guys on opening up headlights. I bought some vision headlamps which turned out to be sealed up like oem ones. I have cut them open on the outer edges and now the center portion where the grill clips into them at is also sealed with the world's strongest sealant. What do you do to get that portion free? I have baked them at 250 for 10 min which doesn't even seem to effect the sealant. I guess I can use my dremel to cut the center portion but I am afraid of hacking up that area and it showing. Any ideas are appreciated.
