Hey Gang! I used R/C 56 on my SD when it was built and I truly loved the stuff! However it is sold under a different name now. I'm sorry I do not recall the name but I purchased it off Amazon Prime and had it in 2 days. However the bottle was so - old it would not move from the bottle. So be aware of on-line purchase of chemicals!

I ended up using clear RTV Silicone adhesive in a very sparing way. It glued in the windows in very nicely on Sig Kaydet Senior Sport! So be careful and manage the silicone and it should work for you!
