Thanks txturbo for your reply.
The polycarbonate shell houses a consumer electronics product. Sandwiching 'chrome' vinyl between two pieces of lexan may add too much bulk to the item not to mention requiring another part ( 2 pieces of lexan vs. 1). Plus the vinyl sheet may not conform to all the countours.
I think using a lexan compatible paint on the inside surface is the way to go. I've found that lexan is popular with R/C hobbyists. There is a chrome/mirrorizing paint that gives the effect of a mirrored (airplane) canopy that looks like it will do the trick.
For those interested, my research has led me to the following.
Mirror Canopy thread on RC Universe forum
Krylon puts out a product called
Looking Glass paint. An even better alternative is specifically geared to hobbyists.
The product is
Alclad 2. See pic, below, for an example of a inside-painted Lexan remote control car body. There are other Alclad 2 products for other metal-look application including color-shifting paint.
I hope this helps others looking for a similar solution.
