Hello everyone I have just got some Fryolux from an eBay supplier to make a small repair to the water tank lid of our Stanley steam car. However, the label has a 08 Feb 2019 expiry date!
I am using solder paint which the USAF threw out 20 years ago, I just thin it with a little liquid flux and it still works fine. I think it’s just the liquid flux element that sets the expiry date.
