and to help before damage occurs. do not bake for 20 mins, all you need to do is preheat to 250 and and when the light goes off(oven gets to temp) turn the oven off and then place lights in the oven for 5 mins. the uv coating will come off if you leave them in the oven with the heat element going. and the sealant can be reused or you'll have to get some taillight buthyl from the nissan dealership(its cheap and you can do a few cars with it) ill post pn if i find it.......
