Here is my problem. Using z5 with zfx on my trans am. Applying it and removing it in the garage. The sun is on the back part of the car and when I am trying to remove it, it is smearing. The part where it is smearing is in the direct sun, the surface has gotten hot from when I applied it. Would trying to remove it on a hot surface cause it to smear? It is dry, let it sit for about 45 min. Used a little less than 1/2 oz on the car. It does not look like it is smearing anywhere on the rest of the car, but hard to tell since it is not in the direct sun. Opinions or has anyone had a similar experience?
