I scoured the forum but was unable to find an answer sorry if I missed it and I'm being redundant.
I'm using dyed Amazing Clear Cast (ACC) as an inlay on cutting boards, I absolutely love the high gloss finish it leaves when cured. Unfortunately, it is almost impossible to pour without having a little over run and when I sand it, of course, it gets all cloudy. I have had success removing the scratches by wet sanding up to 2000 grit but I cannot seem to restore the luster it originally had. I'm able to bring back a little shine when I finish the cutting board with a food safe oil. Is there any way to bring it back fully and remember, it needs to be "food safe", I cannot use a car polish?
I thought I maybe able to "paint" clear on top of the dyed pour but I would need to have the ACC thinned out---anyway to do that?
Any suggestions/thoughts would be appreciated. Thanks
I've done a few boxes with resin inlays in the top and lots of turnings. You're right...there's pretty much no way to not sand things flush. I'll sand to at least to 2,000, but will go up to 12,000 (micromesh, abralon, etc.)for pieces I want a really good finish on. After sanding as high as I want to go I'll either finish with one step pen polish (available from Penn State Industries) of buff out with tripoli, white diamond then carnuba wax.
Never tried the pen polish on flat work - that does have to heat up with friction, so you'd need a buffing wheel that you could run at pretty high speed. Not sure if that's considered food safe - you'd have to research that.
For buffing I use Beall Tools's 3-on lathe system. If you've got a wood lathe I highly recommend that - extremely convenient to have a dedicated buffing wheel for each step all available at once. For salad bowls or anything that's going to come into contact with food I'll wet sand a few coats of walnut oil in, let that cure at least 3 days, then buff.
Both methods work well and should give you a glass smooth finish on your resin.
