In pic #11 of the last batch it looks like you may have a bit of a ''bubble'' in the lower portion of the ''test stab''. If so, thats one of the things I was having trouble with...keeping it stuck down and not blistering here and there when applied to sheet stock or slabs of balsa. I've been able to chase most of them away using a needle to punture the MK and then work the air out. The problem then is the new ones that pop up somewhere else. I'm thinking the iron may be too hot sometimes.
You are right on that, Your yellow monokote wanted to initially buble in certain areas, more so than my white which didnt at all, but after running the iron over them slowly and working them out to the edges, there were very few if any hints of a bubleing left. The way I get my best results is if I just take my time wether it be with monokote, 21st century Coverite, or any other type of covering. The more I rush, the more mistakes I tend to make. I think all coverings work best if you heat them and stretch them slowly rather than all at once.
