Tend to agree with you Dave. A bit hard when you need to order the stuff on line - you don't get to check anything, another problem with online buying unfortunately.
I also checked for Use By Dates - butthere doesn't appear to be any. Stuff stamped on the bottom of the cans BUT, all over lapping making it impossible to read anything - wonderful!
This is one out of a 6 can batch I bought earlier this year. Looks like the lot will be in the garbage and I'll just buy Krylon Matte Clear or similar. Dullcote was so good BEFORE rustoleum got hold of it
