I ride a large cruiser motorcycle, and it has a Lexan brand windshield on it. I have researched online, and it turns out I can only find people who will polish and repair Acrylic windshields. They say Lexan windshields need to be replaced. Phooey to that.
A new windshield alone can run upwards of $200.
These days times are hard for all sort of people. Your 50 MPG motorcycle that costs $5 a month in insurance may just be your best bet to get around. There's no reason why you should have to drop more than $4 to get a clear, safe windshield.
A bottle of polish is under $4.
The windshield on my motorcycle is slightly yellowed from age, scratched up from the harsh desert environment where I live, *and* someone apprently had taped a sign to it at one point.
(NEVER tape a Lexan windshield, it removes the protective covering!)
I would have to look over the windshield, or around it, when I am offroad, to avoid rocks, ruts, etc. I couldn't see through it, and that is dangerous on a motorcycle.
Read on and see what I found out worked to make it clear again.
Step 1: Removing the windshield
First, you have to remove the windshield. It's a little hard to polish while it is still on the motorcycle.
My windshield is held onto a bracket by 4 bolts, two on each side.
Each bolt took a 12MM metric wrench. You cannot reach them with a socket, so grab an open end or box-end wrench.
