Is it just me, or is Towerkote the worst (expletive deleted) ever invented?

I have a pretty extensive background in building FF airplanes, so I know how to build and cover. At least I thought I did. I bought a sealing iron and a Hot Sock and everything, but the TowerKote (dark blue) is a royal pain to apply. At low heat settings, it doesn't stick. At higher heat settings, it takes some effort to get it to stick, but not to wrinkle. Forget stroking those wrinkles out. And the HotSock does not prevent scratching. The Towerkote looks like I was using it to line a wolverine cage.

What am I doing wrong here? Should I have spent the extra money for Monokote? Or should I stick to silk and dope for future projects? Has anyone used Sig CoverAll?
