Please help,,,i have been working with resin for the first time this week,, i accidentally ordered polyester resin and couldn’t figure out the difference between epoxy and polyester resin,, so i had a play with what i had got and was initially really pleased with the outcome but after waiting over 24 hours for it to dry ( a horseshoe style pendant) it was still tacky to the touch so i left it longer, (i had made up the resin using 1% catalyst of the mixture) and so i decided to try another 1 this time using 2% catalyst, this gave me the same result, tacky to touch but has dried.Does anyone else have the same problem? Also when it comes to polishing it its not polishing well and leaving the resin cloudy where i want it clear.I’ve been using wet and dry 600 grit xxx any advice please, i really want to create pet hair resin but really need some advice xxx
