Robert, I have about 4 different brands and I seem to use whatever is in the way at the time. You are right about some being more aggressive than others, I think Walters Solvaset is the strongest. For my toughest decals such as that on the tail above, Polly S is my go to solution. I just checked on it and now there is only minor tenting above the actuator and the wrinkles are all but gone. I have 2 spare roundels so I might cut the red out of one to cover the rip
