I first used SS with great results. The 2nd time I bought a set supplied by PG with the new masking without knowing the change and had poor results. However, for the 3rd time, the new bird from 78TA is also a PG. Learning from the earlier mistake, I put the car in a heated garage and laid the bird out to flatten. This time I had great results though my installer hates the plastic premask. The old paper style once wet and squeegeed gets soft and peels right off. The plastic does not due to the bonding to the vinyl, it is tough. You have to pull it nearly 90 degrees to the hood so not to lift the decal. We also let it sit on the hood for a few hours as we applied the stripes. It is suggested to let sit for 6 hours, if not overnight, especially if you are doing it yourself. For $165 it was worth it to pay an expert.
