I still have o e of the plastil lid covers. They do work but by the time you clean them back up, they are more trouble than they are worth. IMHO.
The timing of this thread is perfect though. This morning I just opened up my first can of SPI Epoxy. I tried the 1 1/2 inch tape trick for a spout. Man do I feel stupid. What a neet trick. It worked perfectly. I have been making messes with paint cans for 45 years and at age 68 learn how to pour paint without making a mess?
Oh well, at least I know now.
