I have an authentic Mugen FRP hardtop, and have owned it for roughly 5 years. I have never used any chemicals or soap to wash it. I've taken very good care of it and it has only been rinsed with water and the car is always garage kept. Suddenly I noticed some spotting etc and I don't know if this is tint or the plastic lexan default window just wearing. Can any of you chime in on how to fix this or are there real glass windows that you can buy? Here are the pics:







I'm sure other Mugen FRP hardtop owners can chime in on this and let me know if this is normal because all in all a glass window would hands down be better if I have to replace this.

Anyone seen this before? Are there glass drop in window replacements?

I bought a hardtop back in 2003 when one of the first group buys was offered. I had the hardtop on for around three years and started noticing the same peeling effect. I called King Motorsports about this since thats who I bought it from and said they could not help me. I believe it is the tint that is flaking off, do you live in a hot climate? Do you use any type of Lexan cleaner/polisher?

Yes in AZ hot as hell here...and no I've never used any lexan cleaners. I've never even used soap to clean the window. Just water and a very soft microfiber towel.

Had the same issue with my top. Fixed it by sanding it down with 1500 grit sandpaper followed by 2000 grit. Use a rubber block sander as you don't want to have an uneven surface. Tape along the rubber seals and buff it out with rubbing compound with a medium speed buffing wheel. Worked great but had to do it every 6 months.

Dang so it's something that must be kept after every 6 months or so. Are there any vendors that offer glass rear window replacements bc then you wouldn't have to buff or sand ever.

I had the same issue with mine, except it was 10X worse. My solution was:

1) Go to nearest pressure washer station (need high power pressure washer)
2) Blast the crap out of the rear window. You will see this layer flaking off. You literally need to get the pressure washer almost right against the window, at an angle, and you will see it coming off from the spray pattern as you move along the window.
3) Get it home, dry it off, and machine polish. Mask the rubber seals so you don't damage them in the process.

I used Menzerna SIP with a Rotary polisher and an orange pad. It looks like new now Clarity is much much improved too.

BTW this is in the wrong section. It should be in the wash and wax section.

I see. Well atleast I'm not alone out there lol. Has anyone been known to drop a real glass window in there?
