Just covered the top of a wing half. I used tape as rip stop and found that it reduced the dip between ribs. I stretched the tape across the wing and then taped the covering to it from the back side. Also tape ribs from the back side in four places on each rib.

Mount that test frame to the top of your car, or the bed of a pickup...let me know how it goes

I build a lot of model R/C planes...Monocote is 1.5 mill thick....Ultrakote is 2 mill thick...the planes I fly are do a lot of manuevers and fly at least as fast as the Ultralight...I've worked with Coverite shrink fabric for models as well...this 6 or 7 mill polyester shrink wrap is stronger...the first time I tried to cover with boat shrink wrap I had to remove it...the spray glue was a bad idea and I wanted it gone...before I removed it, I hit it with a metal yard stick multiple times...it punctured, but did not run...I did see a flat bed truck with shrink wrapped cargo get hit by a bald eagle while going down the road...that did make a hole the size of the Eagle...I bet Stits would too...

If you are on a limited budget like me, the boat shrink wrap and tape is under $300 vs thousands for other coverings like Stuart, or others.

I can build something quickly that I can mount to my rooftop bike rack. I have no doubt the wrap will stay on if I use one piece. I have seen many boats towed on the highway with the wrap. I do want to test a seam. Unfortunately, I wont' be able to get to testing it for a month or two. I will see if anyone in my eaa chapter has a go pro. I know one person who has built a test rig for testing his scale model on the back of a pickup.

I find this very interesting, do we have any real feedback or other news of those who have tried it in the past. Often bad results are not shared however I believe we learn more from our mistakes than successes. That is not to say it is bad but we have no good reports either. Post 13 has something, wonder what the final outcome was. The MATO link pictures show some holes in one place, how did that happen, does it worry the builder?

Where be the holes? You patch them with the tape.

My heat gun died, and I'm waiting on another.

This time I ordered a $17 one with fast delivery.

Summer is slipping away in northern Indiana.

Not worried...used tape from the inside, and thin super glued from the outside. It was caused by me when pulling it over the wing and it caught on a shrp piece of metal and made the hole. It is possible to over heat it and cause a hole.

Yesterday it blew the wings off the sawhorses, and hailed. No rips in the boat shrink wrap, and luckily no damage to the wing halves. I do have a few small indentions from the hail. I just need to reheat them to shrink them out.

do you have name/part # or specifications of what you are using? I see lots of links ebay etc. but not sure what it is or sorry missed it point me to the post number. I would be interested in tensile strength, rip strength, UV protection thickness/ weight, etc. what ever you have. Some of the numbers on the links are pretty impressive.
