To bring back a thread......
I did this about 3 months
Before you start flaming, say I jerry rig things (

), and other things like that, let me say we have been DUMPED on at least 5 times (steady overnight rain) since Ive done this and have been dry as a bone..
I took some electrical tape around the back edge of the gasket. Popped it up, and then applied it to the areas, so the edge doesnt touch the paint.. Then kinda scruntch it up underneath, but it still has flat edges....
You HONESTLY cant tell where it is unless your looking for it... It doesnt look as ghetto as you think it might (if it did i wouldnt ahve done it)..... Ive been high and dry for weeks, and it was free..
It certainly (IMHO) looks better than the mess that is potential with using RTV.....
