More often than not, I fail to read the fine print on a product. However, this go around I did read the back of the LIQUID GLASS can and it says that it can be used on polycarbonate (windshield plastic), so with the new clear Madstad I installed, I gave it the LG treatment. Wow, does that thing look good. Especially since I applied it before any scratches or swirls. I have three coats on the bike, one on the screen, with plans of doing a total of 5. Then its out in the sun this weekend for a bake job. I have to say the paint looks better than ever. Very pleased with the product.
