Re 295 uv: When I used this product my windows sealed well, but the very expensive paint needed to make the sealant stick deteriorated badly where it was not covered by 295. Interestingly, It was supposed to protect against uv rays.

I find it very interesting that the instructions asked me to paint over the sealant and the plexi to keep UV rays from degrading the sealant. I guess 295UV is not too UV resistant. I am debating whether to use Plexus again or 295UV for my next window project. I have both on hand. It would make for an interesting side by side comparison, as I did the port side with Plexus last year.

One of the essential keys is the spacers between the new glass and the hull frame so there is sufficient thickness of sealant. We drilled small holes in each corner and used screws to temporarily hold the glass in place while it cured. It is very sensitive to shelf life, temperature and humidity. As I recall it also recommended the boat be on the hard so there was no movement while curing and something like a week to fully cure Sikaflex has an excellent web site with very detailed instructions - highly recommended reading John & Maryann
