Reglazing my RV windows on my 1989 Toyota Dolphin motorhome. I found if your glazing has began to shrink you can soak the rv glazing in hot soapy water for a few minutes and stretch it back out. I also used 303 spray to help keep them in working order and to keep them from shrinking again! Links on where I ordered my glazing sample kit below, BUT I would def. recommend trying to stretch them with hot soapy water first! I got almost 2 inches of length back!

I Ordered the “Yellow Dot” KRV08523 for my 1989 Toyota Dolphin, the sample kit is only 6 bucks, might as well double check!

Here is the spray I used 303 Protectant Spray https://amzn.to/3NJzGpz
