I goofed today and as I was putting the 4" roller back into the ziplock bag I store it in between coats, my finger accidentally touched the inside of the bag where there was wet paint! I hate sticky things.... did I ever mention I've painted my entire interior with that same 4" roller and a 2" brush? Never dripped a drop anywhere neither! This is not to say I don't HAVE larger rollers and frames and trays, but I was happier dipping into the gallons and rolling it right from the jug! Go figure.....
