I'm thinking of removing a Datastorm unit off my roof and an old TV dish (not Dish), too.
So is it adequate to just seal holes with Urethane? Details, please.
best, paul
I've had very good results with stuff called "through the roof", it's a clear sealant but I'd be inclined to use a sealant and fill the holes with bolts just to be sure.
Just as a by-the-way, the very best sealant there is for small holes, windhield gaskets, and anything on an engine, is Toyota black sealant; you can get it from the dealership.
I filled 46 screw holes on my roof after removing the datastorm and cleaning up other old mounting holes that had sealant applied and was starting to fail. I used MarineTex, Marine Tex, epoxy resin, adhesives, silicone grease, engine treatment, cleaner, (http://www.marinetex.com). Bought it at my local boat dealer. It has a good work time and can be sanded.
