Hello everyone, I am using the TAM contact glue , it is similar to neoprene , in my experience when you apply the glue ( not doing on purpose) somewhere it doesn’t need to be , at the same time you don’t see anything , but one year later it will turn yellowish/brown.... I just put some glue on the fabric of my zipper , I went over the limit I needed to put the glue on . it is invisible at the moment but I want to avoid that it turns yellowish/brown in the future ! What can I do ? Thank you in advance for the tips!
