Slide out side seal screws backing out
On our 2020 Isata 3 FW the lowest 3 screws on the front side seal have backed out (lost 2 of them already) and it looks like the side seal is pulling away from the wall of the RV. I've check screws higher on seal and at back of slide and they all look secure. Questions:
1. Any idea what is causing this and how to fix it?
2. What should I do about replacement screws and securing screws? Would PERMATEX Treadlocker Red work?
3. What sealant should I use to replace the black seal that has come out from between the side seal and the body?
4. Should I add more screws along this side seal?
All help/suggestions to prevent further damage are welcome - Thanks in advance!
