Yeah, in the early 80s we had to swap all the windshields out for bullet resistant glass. My hands were really sore after that. Lol. That's really cool that you built them power houses! I worked for 40 years on the railroad. Welding and cutting on cars and wrenching and supervising on locomotives. Sorry, I don't want to give you any misinformation on sealers or adhesives. Other guys here have more experience with that. Good luck!
