one more thing never use paint thinner or try thinning marsh. also k grade is not even close to as permanent as t grade. another ink to try is pilot or sanford stamp ink.

T grade is the best and most permanent marsh ink to use. do not use pigmented! it is too thick for most markers and can take too long to dry. it is best to use tgrade dye type. that is what is inside the marsh 88hf upgrade of the marsh 88. dye type is better because it drys faster and is thinner. they are both the same in being permannent. just make sure you are using dye not pigmented. you probably are using eithre not tgrade or you are using pigmented.
