Does anybody know the formula for the decal setting products?

It contains a solvent similar to the one found in Testers liquid plastic model cement, I don't remember the name , but what we used to do was take some of the glue and a separate bottle and add acetone water mixture to dilute it...It Works the same as the MicroScale stuff called Micro Sol or Micro Set.

I buy it from MircoScale now.... its not worth screwing up because I had he wrong mixture.

You can use white vinegar in place of Set. Not sure about Sol.
