Hi, can anyone advise me on when I want to finish an item with doming resin. I am doing a 3D L which had a non smooth mould (it’s all I could get!). I need to put resin on one of the surfaces, how do I prevent it running down onto the other side. I tried using sticky tape but it seeped through. The resin is thick as it is doming resin but as the surface is not 100% level it can drip down another side. I worry if I put stickier tape on it it won’t come off or leave a residue. Thanks
