At first it looks great but over time the edges wrinkle. There is probably something I'm doing wrong but it is difficult to heat and stretch around the compound curve and expect the straight line near it to not wrinkle after sitting a while.

Hi Mike.
I have some of the same seam wrinkles on my wheel pants.
Here are a few tips I have found to help (by trial and error).
Avoid seams and material ends on curves as much as possible due to lifting and wrinkle potential.
Avoid seams and material ends on leading edges due to impact wear.
Lap seam overlap should flow aft and down.
Do use knifeless tape. A razor blade will open the film for possible moisture penetration and will scratch the aluminum no matter how vigilant you are.
Apply primer under any seams that are in the slipstream or have any curvature, giving more strength to edge bond.
Apply primer to concave surfaces to give a stronger bond, helping avoid lifting.
When using the primer, the film sticks like contact cement so don?t expect any repositioning.
After removing the knifeless tape and sealing edges/seams with heat then apply clear seam sealer product.
Hope that helps?Cheers!
