Scratch on window

I never did it,but that is what I heard and read also.

It depends how deep the scratch is. If it's light enough, Future might do the trick.

I usually use a fine grit stick down to polishing grade then polish with Simoniz Swirl and Haze Remover and it looks like real glass.

Actually, any self-leveling gloss clearcoat will have that effect. I have used Future, Glosscoat, and a clear acrylic spray.  All seem to work for very minor scratches.

Hi ;

Everyone has given you pretty sound advice .What I would do is this .See if you can feel it with a light pass of a fingernail  .If so then do this . Can you remove the window or window unit from the model without damaging it ? If so then sand it WET with 800Grit to get it smooth then graduate to 2000 grit .

After you've done that then use NOVUS polish and then the NOVUS protective coat afterwards .Or just polish it with ToothPaste NOT gel , and then dip it in Future .
