In years gone by, it used to be 1:1:1 Trichloroethane as the ideal thinner. I know that was outlawed.
Have several bottles of genuine Tipp-Ex (as apart from some water based stuff) The Warning triangle states Highly Flammable - so still solvent based.
Any of the Chemical chappies on here know what I could use as a thinner? ..... I have some of the more common ones - meths, acetone, cellulose thinners, Trichloroethane , ISO-propyl alcohol.
Bar code tells me it is Tipp-Ex Rapid made in Germany. It is Art No. 4002523 09 UPC 0 7033051106 4
Wikipedia says that has now been replaced by Aliphatic Hydrocarbon, and also now uses a foam brush. The containers I have still have the original 'brush' ..... so unsure if the product is with or without Tricho
