i have some solvent cleaner from my work that works very well at removing deposits of spray glue and foam backing the carpet will leave, i used QD90 macheane paint and it seemed to work quite well but patches are wearing.
after reading this thread i think ill use up the 3litres of 2pk black i have left from my build on my new deck next year
if you need some of the solvent cleaner gimme a shout john, works real well an gives you a nice head whilst using it!!
