Repairing a small chip using weldon 40

[tadpole]

I have a small chip (pinhead size, 1/32" deep) on my display tank. 3/4 inch acrylic. Too deep to buff out. Would applying a very small amount of Weldon 40 to the inside of the chip help minimize the appearance?

thanks!

When it dries, it will leave a blob behind. There is no good solution, and some many even make it worse than doing nothing.

For example, you can use the solvent to dissolve some acrylic shaving, and make a very thick/viscous glue. By making sure there is no air bubble in the glue, and by prepare the chip to ensure the glue can adhere to it without visibly noticeable "interface," you can put the glue in the chip area, overfill it a little, and when it is all dried, sand and buff it down so that it is at the same level as the rest of the surface. But the preparation of the chipped surface may need to enlarge the area, and if any of these step goes wrong, you will end up with something looking worse than before.

Maybe acrylics can have some insight as to the proper method to repair chip.

Sorry, haven't been around in a while. If the chip is on the corner, best bet is to machine the corner off and then re-buff. For example, use a radius cutter in a laminate trimmer and round over the edge and then sand and buff the newly machined area. You can buy 1/16" radius cutters at any wood supply house.

To try to fill it in creates the risk of crazing and the new material will not me the same "color" as the original tank material so will be an even more apparent inclusion.
