Taping Window on Cab Over

I had a painted aluminum siding camper years ago on Alaska trip. I used a 3/16 mahogany door skin and painted it both sides for waterproofing then cut it to shape of front glass and used similar colored Duct tape on siding to attach it. Never had a rock strike, but it made me feel better knowing my bed was not going to be wet and covered in glass!...in my experience Duct tape glue has never hurt painted Aluminum or Fiberglass siding. Varsol and a rag and a bit of elbow grease cleans it up. I have had Duct tape cooked on in AZ sunshine on my Bigfoots many times and hardened glue left on camper when tape is pulled off always comes off with Varsol.
