right all u painters out there im on a tight budget and im painting my tank
the tank is grp ive prepped it and stupidly put acrylic primer filler on straght away it reacted ...rubbed the bad bits down and gave it a once over with the sander...this time i put some etch primer on it better but still reacting in small areas is ther something i can get to stabilise it or is there another reason for this unique to fibreglass? ta
