Based on my earlier post asking about installing an aftermarket convertible top, I decided to clean up the one I have on my '66 small block. I am planning on using Maguires Plast RX on the rear glass to deal with the fogged glass, etc. Thoughts on the process and/or using this product, or another? Also, any suggestions on convertible top cleaner/conditioner would be appreciated? I would like to avoid making a catastrophic error that would make me change the top. Thanks!
