What UH said is important. If the double sided tape failed on the Mylar side, you can improve the bond to the double sided tape by roughing the surface of the Mylar. Use masking tape to protect the half that is not to be bonded and then give the surface some tooth with abrasive paper.

It's important to press the Mylar down firmly onto the adhesive. A ball bearing mounted in a notched wood handle makes a good roller. After rolling down, position control surface so it's not trying to lift Mylar. Full strength is gained over about a day with most tapes.

Thanks, bumper, I'm heading to the hangar today and pull the glider from the box. I will take a better look at what the issue is. So a ball bearing works as a good tool for this? It sounds like your getting pressure in a very small area to help seal it.

When I first flew it after the resurface, I heard some chattering outside. Ok what's coming loose! And you can't blame high-speed pass since I hadn't done one yet! The new air duct that was put in made the sound more intimidating. The 27 sounds completely different from the air scoop behind your head. Ok, I'm ranting... See ya... Thanks again... Gary
