So finally found a tach for my 65 ss.after over 50 years of well intensioned cleanings,the lens is kinda hazy. Any ideas on how to polish it without making it worse? Or is there anything in the repop market yet?

Contact ChrometechUSA. Maybe Bob will tell you how he polishes the ones he gets or maybe you can send yours to him.

You can use the lens from a vacuum gauge.

Find a shop in your area that sell Plexiglas, polyethylene or Kydex sheets to businesses. Regal Plastics is our local supplier. They should have several plastic cleaners in various grits for polishing Plastic, I can't find any around here right now to give you a brand name but the stuff works awesome.

Check with your local motor cycle shop. They have products to clean and remove scratches from wind screens.

Maguire’s Mirror Glaze has always been my go to plastic restoration product. They make it in cleaner and polish.

First heard of it being used on airplane Plexiglass wind screens. Also motorcycle screens. Have even used it on plastic eyeglass lens. And a bowling ball, but that’s a different story.

went in to the harley shop near here and they use a product from novus- heavy scratch remover made for plastics. i tried it and after three rounds of polishing it works. cleared it up pretty good.the lens from my old vac gauge looks a little better but this will do.

Novus is a great product. Mil Spec and used on military aircraft canopies and windscreens.

I bought 3 bottles of Novus years ago.
#1 is a spray for finishing and cleaning, #2 is for fine scratches, and #3 is for heavy scratches, but if you can feel a scratch with your fingernail forget it when it comes to hand polishing hard plastic with Novus.
Always seemed weird to me that #2 is a tan color compound that seems coarser or more effective than the #3 that is a white color compound?
Maybe the bottles got filled wrong?

I got mine at the Harley shop. It is the Novus 2 for fine scratches. It did take several times over the lens. Doesn't look just out of the box brand new but looks real good.

Ryan, for the bad scratches, I use Comet cleanser with a little water to make a paste, or even toothpaste. If the scratch is bad bad, then wet-or-dry sandpaper is in order (400-2000 grit) before polishing out.

Thanks Tom, I had scratched and scuffed factory optional door speaker grills on the Mustang and used 0000 steel wool to start.
It left them smooth and dull, then the Novus polish brought them back shiny.
