Does anyone know what to use to take out age scratches on the plastic lense covering the speedo , guages and clock?

Braso works good on plastic. I have used to repair a DVD that my daughter slid movie side down across the kitchen floor a few times.

If you have a Harley Davison shop near you might check them out. I used two different products made by Novus. One was the fine scratch remover and the other the polish. Good product used by some fussy bikers.

Before buying anything try some toothpaste. I used it to clean up the lens for my car and I thought it was junk before I started because it was scratched badly and had overspray and such on it.

Depending on how badly your lens is scratched, I would not use brasso or toothpaste if you just have minor superficial scratches. Try the product that Dick recommended. It is actually made for plastic scratch removal.

For the scratches I would try a prodict from MEGUIARS they have for plastic parts there are 3 steps total to it one is a cleaner the other is a polish and i forget what the 3rd step is but it works VERY well i used it on my rear convt plastic window that you could not ssee a thing out of and it brought it back to crystal clear i was impressed. any good motorcycle shop also would sell acleaner/polish kit for helmet shields that would work well but i have used the meguiars stuff on my own car and it worked great

here this may help more meguiars partM-1708 plastic cleaner M-1008 polish and M-1808 detailer

I like Novus. There are places that sell it online (TAP plastics, Pinball Resource)
Great stuff!!!

I buff them with medium rubbing compound and a wool pad............just like rubbing out paint. They come out perfect.
