Gaco silicon roofing vs liquid rubber roof and eterna bond

[sunovertone]

Hello travelers. I have an older 1999 Thor trailer. A tree branch hit the roof, and took off part of the roofing. Everyone said we should use Gaco, a silicon based product. But it doesn't seem to be working very well. I am wondering if I can apply liquid rubber roof over the Gaco silicon, or will I need to remove it first? I am not exactly sure what the roof is made of, or even what the diffrences are.
Also, I am thinking we should eterna bond patch the hole, can I apply this over the Gaco? If I can not remove the Gaco, and the liquid rubber will not bond, should I use the Gaco tape and more Gaco? Also will Dicor sillant still work with the gaco?
I will try to figure out what the roof is made of, but I think it is fiber glass, as the sidings are! Thank you for any expertise!

Sasly, nothing much sticks to silicone including itself. On a trailer that old the roof membrain (rubber) is very likely dead. So there is no real good answer for you. For a cheap fix, remove all the silicone infected material. Clean everything thoroughly, patch with eternabond if possible and then cover the whole roof with Dicor roof renew product.
