I'm questioning something here. I purchased a tank at one of the local shops in Nov. 2017. The tank was an rda it was an okay tank but I found I didn't l like dripping when out. I cleaned the tank roughly dried it went to the store. Came back and the screw was rusting. In my head I'm like wtf! Part of this is my fault I couldn't get the screw out and didn't immediately bein g it any where. Well I went to another shop recently and he asked me to bring it to him and maybe they could fix it (I think he thought it was dried juice). One look and he for sure confirmed rust too. Called shop I purchased it from and asked if he would take a look. He looks at the tank just as shocked as me but he generously changed the screw for me. Here is where my question comes in... the new screw looks clean but the surrounding area has rust residue. I asked if he would use the tank and he said yes. Would anyone use this tank? I thinking even if I scrub the rust off is it really all gone? Can't open the deck to check inside, it is not made to be opened so idk if something is rusting inside. When i shake it i can hear something jiggling inside. Had anyone else have this happen? Really bummed I forked out $40 to support a local b&m and now this.
