Re: Lexan/polycarbonate vs acrylic
The thing about VHB tape is that it wants to see perfectly matching contours. Flat on flat or curved to curve, they should mate flush if you want the VHB to bond them. If you can grind or fill to make that happen, call 3M's toll-free number and someone will be able to tell you the exact strength that tape can provide, probably "xx pounds per square inch".
