Have you ever wondered how to get polyspan to form around curved wingtips with no cuts? I filmed a demonstration given by Roger Kramar as he covered a wing panel with a curved wingtip using a single sheet of Polyspan with no cuts.  He shows the process of using a monokote iron to tack and shrink the Polyspan around complex curves.   He and Gordan Delaney have used this method for many years on their beautiful front row quality ships.

A really useful show of how to do a wingtip ended panel. I learned a lot! Forms a perfect base for my following rant.

Unless you are going for a Nationals 20 point finish, look into covering the polyspan with park flyer film.  Instant colored composite finish that has proven remarkably durable.

If you are going for the top quality finish, scuff the outer surface of SLC film, cover and you are ready for your top coats of paint. No primer and prep required. Lighter, tougher, cheaper, quicker, durable, less dope fumes, what is not to like?

See the SLC over Polyspan thread. Can 112,000 views be wrong? Try it and let us know. A lot of viewers are looking to see how it works. So far the reports have been positive.

I have used this scheme for years and would never switch back to tedious, multiple layers of dope to fill a porous covering material and then try to make it shine. Life is too short for that.

By the way, Hi Gordy! Haven’t seen you in a long time. 🤠

One of the nice things about adhering Polyspan with ModPodge is the ability to shrink, stretch and stick the covering all in one step, like any other iron-on covering. Somehow, ironing wet dope "goes against the grain" for me, but I can't argue with results.

Thank you Brent for sharing this with us, great useful information.
