I thought I would throw this out there to hopefully avoid having someone else from getting into the same situation as I am in.
I have tried to use 3M Hi-Strength 90 spray adhesive for installing reflectex and headliner materials. It claims on the can to be "heat and moisture resistant".
Additionally, I have now bought Weldwood Contact Cement and have come to find out that you will end up[ with the same problems with it at the 3M 90.
The problem is that neither of these products are designed or intended for the high heat inside of a car interior which you might encounter in the hotter areas of the country like Tucson AZ.
I suspect that in more moderate climates near the coast that you will not run into these problems. I used to live in Santa Barbara county and never ran into these problems before.
The issue is that these adhesives become gummy and never fully cure. They basically remain in a rubbery sticky state and never develop or at least eventually lose any strong adhesion properties.
3M has recommended an alternate product for automotive applications
Product ID 38808
And Weldwood recommends a similar alternative product
Ladau Top and Trim adhesive.
I'm now in the process of trying to strip off the gummy material using a 36 grit flap wheel. Solvents really do not cut the rubber material so it is only through a physical action that it can be removed.
