acrylic crazing repair ideas

[BichirKing]

so after using weld on 40 to reinforce the seems I noticed that there is now crazing on the end panel 24"x24". some are deep enough to catch my fingernail. my thoughts were to have another piece of acrylic cut and using the weld on 40 to join the two putting the new piece on the outside, kinda like laminating the 2 together. or cutting the new panel 1/4" short on all sides and putting it inside, using the weld on to fill the gap between the sides and the new panel. but that would leave an air gap between the two that I think would not be as strong. what are your ideas or thoughts?

Crazing can be sanded out. I would do option 2. Cutting it slightly shorter. Will be unsightly though

I think I could try sanding it. I have all the stuff to do it. I just finished cutting and buffing the front and sides.

after but still needing the novus polish.

If you are going to sand it out start low grit. I’d recommend as low as 220.

Yup will definitely take a while. Crazing is deeper than most scratches

will it make a thin spot possibly?

Makes sense if this would show good result using 220.

Depends how much sanding is required to remove the crazing. It will make a thin spot as you are removing material, but 1/16 of an inch on 1/2” material is nothing.
