What spirit is used to make spirit stain is it Thinner's or meths Frankie.
Meths it has another name in the US.
Meths it is for spirit stain better buy the clear stuff of leave the pink one on a window sill for a while and it will lose it's colour
Or strain it through an uncut loaf of bread.
An old aboriginal trick, they dont like coloured metho either.
Can do the same with red diesel "apparently"
