Can fluoropolymer coatings that are still very glossy be overcoated (if, for example, the topcoat is losing color or the color needs to be changed)? If so, what type of coating can be used, and what surface preparation is required?

From Warren Brand of Chicago Tank Lining Sales, Inc. on September 25, 2013:
My understanding of fluoropolymers is that they are exceedingly difficult to overcoat. Of course, the correct answer is to go back to the original coating manufacturer and get their advice. Without knowing more, I suspect that you would almost certainly have to scuff the surface to gain an anchor pattern and then determine coating compatibility between the fluoropolymer and new coating on top. This would need to be researched and ultimately checked by conducting appropriate adhesion tests. The problem is that the adhesion tests will only tell you what the current adhesion characteristics are at the time. They will not provide any information on the long-term durability of the new top coat or the long-term compatibility and adhesive characteristics between the fluoropolymer and topcoat.
