This video details IMHO the easiest NWT method I’ve seen yet… with darker grays and blacks, faster jobs, and water cleanup. I followed his super-easy recipe [initially] to the letter and later substituted Floetrol for the glue… i.e. 3 parts water, 1 part Elmers school glue/Floetrol, 1 part TiO2 powder, and a few drops of food coloring. Lightly brushed on… not messy at all and super-fast cleanup.
