I was sort of stuck with this rubber seal issue, and it had clear silicone gobbed over it 1 inches past each edge, and 1.2 inch thick in literal gobs. The same person must be going around the US with his Silicone shotgun! It was hard to tell where the leakage was coming in from due to the peaks and mess it was. I needed to get it ready to hopefully go on a long trip in two weeks so no time to do much of anything, as I need to go through the rest of the Toy to check out whatever else I can. What I did was spend three days trying to get the worst of the clear off, which was a mixture of clear silicone and clear -something else that was hard. (some epoxy?)
Silicone remover helped with the true silicone, but then I had to try to razor off the hardened stuff- (only was 50% successful, before I gave up)
I did get the worst of it off, so your eye was not drawn right away to that mess. Then I taped the rubber seal off and used black silicone over the whole seal. I considered the Gorilla tape that I love, but as it was still not just perfectly smooth rubber, the tape would have left small gaps on the rough edges still there. (that stuff is also a bear to remove down the road) My silicone idea was a great temp fix-except for one mistake. I used 3-hour black gloss and what a huge mistake! It was hot outside, and after I beaded it on, I was very happy. It was looking good-until I tried to smooth down the beads. It took me only about 5 minutes to lay the bead around the seal on each side, but when I tried to smooth it over with a wet brush, it was already set up and dragged, leaving me with a slight texture like surface. Not what I wanted! I will never use 3-hour silicone again.
It is what it is for now, no time to spend on the window replacement this month, I will put black-out window cover on the inside, so the light does not shine through and highlight it and a black out curtain,
Still it's a 100% improvement, and will not leak, but I would not ever use 3-hour again, as there is no working time. (it has a super gloss, and a deep black though, and that deep black is hard to find)
