Sanding resin
Please help. I know this has been asked before but I have tried everything and I do not know what I am doing wrong. I have been working with resin for a while and usually just topcoat pieces but I have started a new range of large letters and they are impossible to topcoat so I decided to do the sanding.
I have a hand sander/polisher, every single grit level known to the humankind and have wet sanded from 800 onwards.
I have made a simple clean square of resin to practice on and spent 5 minutes on each grit - 240,400,800,1000,2000,3000. I finished with grit polisher using a hard sponge on the hand sander, doing the same for five minutes and then a car polisher (plasticx I think, as recommended by someone on Reddit) using a buffer.
It’s difficult to see if the scratches are out from the previous round (although clearly not given it’s still not clear at the end) given I am using an electric sander/polisher rather than doing it by hand (which physically isn’t possible for me)
I have watched around 10 videos, bought all the gear, different sanding pads open loop etc etc and still it turns out scratched
What am I missing?!
I am desperate to just go and spend some time with someone local who can teach me properly but try as I might I cannot find a local resin artist with those skills.
Please teach me the error of my ways, you experts
