Grind the hair out, mask that section off, re pour. Wet sand then polish. It should match up perfect if your polishing skill is up to task.

Anyone got any tips how to remove a fine hair from cured resin?
It’s a largish table with glasscast 50 and a flood coat of glasscast 3.
I don’t want to sand the whole table down and do another pour over the top just for a small hair.
There must be something I can try instead?
