dont make this another oil thread but trying to remove kreem from my Eldo fuel tank and using MEK with some success but not great, the pieces that are coming out are still intact not dissolved which I believe is the case , I experimented with those pieces by coating them with a PVC pipe glue primer which is made up of tetrahydrofuran , MEK, cyclohexanone and acetone and it appears to turn it to a mush which is good but before I go out and spend money on this primer has anyone else used it with success thanks Ray
