I'm pretty frustrated right now. Today did not go well.
On Friday I purchased some auto body seam sealer to use to fair in the edges of the windscreen fairing. Today I attacked that job, and it didn't turn out well at all. I had put some vinyl tape on the outer surface of the windscreen fairing and on the windscreen where I wanted the edge of the bead of sealer to be. When I put the sealer in place I tried to keep it just on the area I wanted, but some of it spilled over onto the vinyl tape on the windscreen. When I was done, I pulled the vinyl tape off, but the sealer had already started to skin over, and pulling the tape off left a very ragged edge in many places. I was really freaked out, as I had this ugly disaster on the windscreen, and I didn't even want to think about having to buy a new one, and redo all that work.
I took a deep breath, and looked closer. The left side (which was done first), was completely ugly. The right side, was much better, as I was much more practiced with the seam sealer, and had much less sealer on the vinyl tape. I decided to see if kerosene, one of the very few solvents that is safe to use on plexiglas, would soften the sealer. I was greatly relieved to see that it slowly dissolved the sealer. It took quite a bit of time, but I was able to remove the bulk of the sealer on the left side. I'll give the remaining sealer a few days to set up, then I'll have to try again.
