Hey Tim. Do you have a recommended source outlining the process you used?

Randy, I used the exact same method as the SilPruf that's documented on the YouTube series, except I used Sikaflex instead of the SilPruf. The Sikaflex is not silicone based and therefor (in theory, according to the MFR) can be painted over if desired. I mainly used it because it's UV and you can get it in black. I also wasn't as paranoid about cleanup since even residue of it won't affect future painting.

The primer for it is a bit expensive, but still not terrible compared to the cost of the build.

I'm just not great at fiberglass work and I did not want any chance of paint cracking down the road.

Thanks Tim. I just started watching this series yesterday. It is quite good so far. Iíll have to look into the benefits of Sikaflex as well.

Google search Glasair Sportsman window installation. You should come up with a five part instructional series someone did. Walks you through the process. Except for the windscreen the Sportsman has the same window joggle. With a little modification, it can also be utilized for the windscreen. I used Silprof. Others have used Sika. You end up with the same results. Silprof is silicon so it’s 100 percent UV and waterproof. You need to be carful not to get it on anything to be painted in the future or your paint may fish eye. Sika is not 100 percent UV proof and could break down over time, but the way we take care of our planes once built, probably will not make any difference. Watching the video is the best to do.

I am planning to do silpruf on mine so I hope you have a good experience with the final product. It'll be some time before I get that far in the build, so I expect to hear good news from you by then!

I used Sika on my -9A tip up. Lots of research and anxiety, but in the end it was a breeze. Couple of things to note - 1. Iím not flying yet, so... and 2. this stuff is messy. In my mind every bit as messy as pro seal. I didnít tape off enough area and made quite a mess.

Working time with Sikaflex was not an issue, and glad to have avoided drilling the canopy.

I am doing sika as well. Plan to do it next week, as I decided to leave the windows out as I wrap up my wiring this week. Windows are all cut and prepped. Way easier getting in and out of the seat 200 times without the windshield:-) The 295 UV is what you want. Only available in black. You need a specific activator and primer, but I don't have them handy, but will post tomorrow unless Tim beats me to it.

Larry

I like this idea. Definitely more a fan of black window sealant than the grey-silver silpruf.
