Ive applied 3 coats of stain and 1 coat of intensifying over a 2 week period,everything was looking good. On thursday applied a finish coat after a light rub with some 600 grit, and left to dry, checked the next day and coating had blistered in different spots. So i have let it dry for 3 days and rubbed it back to smooth on those spots then steel wool 0000, wipe down with some gum turpentine and let dry. Did another coat this afternoon and its blistered again its like its not adhering to the intensifying coat. I did the neck coat at the same time and its fine.
Any ideas of why, the humidity shouldnt cause this only slow the drying time
Thanks
