Tried the silca base grit and it does not do much. Anyone have experience with an affordable shop that can remove light scratches. Found a place in Camarillo but they have not called back

What kinda light scratches are we talking about? Is the glass etched?

Light surface scratches from improper storage. Deep enought it will catch your finger nail.
I have seen some info the acrylic nail pilish works but i cn see it building above the scratch. I may experiment on a really bad window to see how that works.

I wouldn’t consider a nail catching scratch light. I’ve filled a few cracks with windshield repair kits, been impressed with the results (not perfect, but loads better than the bubble or star that resided previously). Perhaps something like that would help.

If you can feel a scratch with your finger nail, nothing will take it out. Cerium oxide exists as a polishing agent and being in the window business we have tried it many times with little/no positive results. New glass is the answer, I just had a new windshield installed in one of my 914's locally for less than $300. No brainer

In my experience windshields are far more 'polishable'
Side glass is manufactured a different way and doesn't polish at all.
I've tried with the available kits more than once. For hours. No dice.

These are side windows. There are no new replacements.

Just thinking out loud here, but my first thought is the same as what @http://www.914world.com/bbs2/index.php?showuser=9463 suggested, plus a polish kit to use after.
If you can get a nail to catch, then there's no way you'll be able to polish through it. So, if you can use a UV activated filler, then maybe you can polish out smooth. with something like the kit offered from eastwood:

for my glass maintenance, I've been a long time user of '0000' steel wool. it doesn't really cut into the glass, but it does a great job of removing embedded debris and restoring that squeaky clean feel.

You might give 'jeweler's rouge' a try. Pretty inexpensive. Cheaper than buying and shipping a used piece of glass (no idea how to safely package it short of building a wooden box). There are plenty of YouTube videos that show how to use rouge to polish glass.

Windshields are laminated glass (two layers of annealed glass adhered with a PVB interlayer), side and rear glass is tempered glass.

As far as the scratching, we have found no product with any abilities for removing scratches. and being in the glass biz for 40 years I know of none.

Please enlighten me if there is such a product
