The salon windows have been curing for over 7 days, so it was time to remove the clamps and blocks that were holding them in position and apply the remainder of the sealant to finish this project.
After breakfast I once again masked off the area around the windows in an attempt to try and keep the black goo from getting all over the gel coat. Between all the masking and the paper towels, I'm starting to wonder if there isn't a joke about how many trees you have to kill to install a plastic window.
After masking everything, it was time to see if the window holds without the clamps. I slowly removed the screws and fender washers, watching the nearby edge of the window for movement. The windows didn't budge as the screws were removed, so I now have proof that they not only don't leak (courtesy of the rain a few days ago), but seem to be adhered in place. Yay!
|Some of the project supplies and tools|
I noticed there were a few places where I could not see sealant squeezing out of the back edge of the glass where the screws and blocks were, so I started by cutting the nozzle on the first tube of sealant rather small and trying to inject it into the voids. I then used my bent putty knife to push it around and pack it in behind the glass. Trying to work sticky goo into a 3/8 inch gap and around a corner is...lets just say it tries your patience. I then used the smaller nozzle tubes to fill in the back of the remaining gap between the window and the opening.

Finally, I cut the tip to a larger bead and filled in the remaining gap. Someone who does this for a living could probably make it look nice right out of the caulk gun...but I am not that person. I ended up using my scrap from the flexible cutting board that I used on the anchor locker repair to "tool" the sealant edge. This produced a reasonably nice looking joint.
|Windows all installed.|
But only to a point. The sealant started curing a bit and by the time I got all the way around the window, the joint didn't look as good. The stuff takes up to 21 days to fully cure, but apparently will start getting tacky in under 15 minutes. Oh well. I'll have to live with Bill's 20-foot rule....if it looks good at 20 feet away, it is good enough. Removing the masking and the film that protected the glass was equally challenging as it was starting to skin over. If you ever try this, try to have an assistant or two available so you can do these steps fairly quickly.
|I can see outside again.|
In the end, I only needed 13 tubes of sealant for both windows. I guess those that needed more didn't do the second ring of foam 5/8" from the edge of the glass and probably also used the 1/2" foam so the window was flush with the opening instead of recessed like the original installation.
So, all the sealant is applied and one more big project is ticked off the list. Good thing since I want to be headed south in a week.
