Hi Bill. I do have better results with the higher iron temp. Using the transparent going over some of the balsa sheeting has been a real eye opener. It shows you where you get a good bond to the wood and it also shows dulling easier than opaque. My only trouble is the effect known as "elephant skin". I guess in years past I just worked that little wrinkles out with heat but on transparent covering the glue underneath still shows that "elephant skin" even after the surface is pretty smooth. I encountered the "elephant skin" at both lower temp (say 300) and also in the 350 range. Any ideas on how to eliminate this? It seems to happen most when in the tacking stage.

I have to admit that Monokote has a steeper learning curve than Ultracote, but the superior adhesion and better finish has me switched back now. Its a bit more work when building but in the long run you probably save time by not having to re-shrink your covering every time your plane is in the hot sun.
