Hi Dave

 

One piece of data I have from Dow shows that black can get to 190 degrees F on a warm summer day in Michigan and olive can get to 180 degrees.  Red probably would be fairly close to olive since white was up to 135 degrees and milled aluminum was at 165 degrees.  I have seen another chart that went by colors but I'll have to see if I can dig it up.

 

Your technique of building a high ridge of adhesive and squeezing the skin into it is also important for bonding.  It helps eliminate trapped air and thus avoid..., er, voids.  Anyone that has ever applied an adhesive logo and worked it from the edges in knows about trapped air in the middle.
