Hi John, what resin are you currently using? For filling a channel in wood, typically our
GlassCast Clear Epoxy Surface Resin
is a perfect choice. If you look at this picture, we literally poured the resin into a mixing bucket and then easily shaped the resin with sandpaper before polishing back to a gloss:
Hopefully you should be able to level off the resin in your situation then bring back to a high gloss relatively easily. You may find you need to leave it a bit longer to cure before sanding if you are having difficulties.

Hi John. You'll need to work to much finer grades of wet/dry abrasive paper. To remove the light scratches created by the 240grit, you would need to use a 400grit and then an 800grit followed by a 1000-1200grit before switching to a cutting compound to bring up the final gloss appearance. One tip is to change the water between each stage to avoid picking up any loose grit from the previous stages.

This partly answered a question I had too. I’ve sanded cast acrylic rods (bought as solid, not cast myself) to high gloss before using 1600 grit paper after cutting. With “self cast” I’ve seen...

As casting resins go, the only product we have that cures with a tacky finish in air is our Water Clear Polyester Casting Resin. However that is easily solved using Solution MW Wax Gelcoat Additive
