hopefully this is the best spot for this question.

First I will say that I've covered a dozen or so planes so far & felt like I was getting pretty good at it. I am doing a repair for a club member on a Sig Sukhoi, the big green/cream one. He bought Sig covering (Aerokote I think).
I cannot get it to stick to the wood. I have tried various heat settings etc. Even got out my backup iron & tried that. I've NEVER had this problem with either ultracote or Monokote.
I'm trying to iron onto fresh new wood sheeting, not CA soaked or anything. Sanded smooth. Just as soon as I lift the iron the covering comes right back loose.

Any suggestions? wood sealer?[:@] It's like theres hardly any adhesive there.

Thanks,
Ken
