I hope it doesn’t undermine the VHB. Here is where I got the idea...  there
is another thread somewhere about it too but can’t find it now

“If the color of your plastic is not dark enough to hide the grey tape (and
sealant), you may want to paint the inside perimeter of the pane. This will
also protect the adhesives from potential UV attack, but the bond strength
will depend on the paint adhesion. According to some professionals,
silicone-based, high-temperature exhaust paint is both compatible and
tenacious. The area to be painted is the area exposed when you remove the
ring of film.” Don Casey

Won’t that undermine the bond with the 3M tape?

My plan is to paint the acrylic underside with VHT Silicone header spray
paint.  Saw this recommended on a forum somewhere .  Anyone try this?  Good
or bad idea?
