Hi Biggyniner,
Since your unit originally had a silicone based sealant, you will want to use that same sealant. The Dicor lap sealant will not be effective in this circumstance because it will not stick to silicone, and you will likely have some silicone residue left on your roof.
Hope this answer is helpful and good luck with your repairs. If you have any further questions, feel free to call Dicor at 574-264-2699.
Safe and Happy Travels!
That makes sense for patching I suppose... For whatever reason the screws around the tank vents were not covered in a sealant... i used Dicor on these since there was no previous sealant.. Hopefully that does not cause an issue.
