Hi to resin experts on this forum..... Sorry if this question has been asked previously, and I did try a search before posting. I am wanting to add something to my resin in order to change the colour of the part produced following moulding and casting. My first thought was to add one or two drops of food colouring to the A part of the two part resin mix, then mix it thoroughly and add the B part as normal. However, I am worried that if the food colouring is water-based then the curing process of the resin will not work properly. Would something like a tube of artist's oil paint work better, or possibly clothing dye? Any thoughts from forum members would be much appreciated and also any personal preferences for this type of work. Thanks guys. David
