Interesting video, they do say the Vallejo is better for their paints.
Recipe
Water 40ml
Isopropyl Alcohol 20ml
Windsor and Newton flow improver 1ml
Windsor and Newton Fluid retarder 1ml
and Bob is your uncle!
Initial outlay expensive, but it will make loads (I recon it will cost £15-20 to get going)
Hahaha Zak I would love bob to be my uncle lol
Yes your right about the price but you can make lots and lots
It works extremely well I've bin using it for about 4 months plus with vallejo paints and have had no problems with using it for vallejo thinners 200ml is about £15 so in the long run it's cheaper to make your own
