A trim stripe must be sealed by some method. If they are narrower than about a half an inch you could use heat and not have to worry too much about creating bubbles underneath a stripe.
However, I've found that sqirting the plane with windex befor you apply the stripe allows you to position/ and re-position it several times before you permanently seal it.
You must let the windex dry overnight!!!!!!! It will blister if you don't.
I'm learning to appreciate trim solvent more every time I use it. I will probably start using it for trim stripes as well.
Take a Q-tip and dip it in solvent. Dab the Q-tip on a paper towel to get rid of the excess. (too much can melt the monokote and make it bleed) Then run the Q-tip down both sides of the trim stripe.
Thats pretty much it.
I learned most of what I know from one of Gators' posts on RCU.
