This is not a bad kit but does need a bit of filling. I used my chosen filler – Milliput along with some IPA , a needle and a scalpel to have a go at this. I’ll be using some silver paint to look for issues with my efforts so far. This filling was very fiddly and seemed to take forever. There’s a surprisingly large amount of grooves to fill. I’m yet to do the one in the bottom of the mouth
