diamont toners are basecoat. there is nothing concentrated about them where they need binder...mostly. anything that is on the rack in the can, you can just reduce, pour in a gun and spray. where binder comes in is the pearls in the small bottles. when you add those to the basecoats you need to add 3x the binder by weight. binder being bc100. so if you had a formula with 100g black and 10g of blue pearl then you also need to add 30g of bc100 as an additional binder for the pearl being added. the only thing that doesnt apply is the pearls that are in the quart cans. those are basecoat like all the others and can just be added. as for you system 88, i have no idea what that is. never heard of it. i dont think that is any part of the diamont system. i had a diamont rack for 8 years and never saw any product that said that on it.
