Does anyone know a method or cleaner to bring back the lexan/plastic portholes on my 25.5' back to near transparency?

Rubbing Compound

Our lenses were scratched and discolored, I started out with a medium abrasive rubbing compound and finished with a metal polish.

Novus

I cleaned and polished my 19 year old opening ports this spring with the 3 step Novus products, they are almost as clear as new. It has been 3 months and there has been very little change in clarity. I bought the Novus products from TAP Plastics, www.tapplastics.comgreat product.
