Take Two. OK, so... here we go. Painting for dummies. I'm gonna detail the steps involved in painting. Here's the tank we're using. It has a single vacuum petcock on the left side, so 80 something Special? Inside is clean as a whistle. Maybe one or two very light spots of rust but no pitting. A few minor dings here and there but overall good and straight. Here's the bad. The existing paint. It goes on forever. At least 4 coats that I could see.... with prolly a quart of primer 'tween each coat. What a mess. I've learned from experience that when it's this bad, stripper just turns it into a messy goo. So I drug out the 3" disks (#60) for the die grinder and went to town. This little bitty tank took about a dozen disks. With that aggressive a grit, as soon as I started to see metal, I stopped. Once it was down to the last layer, I switch to red rolok disks and took it all the way to metal. Too late tonight, so tomorrow I'll use some stripper to finish off the little nooks and crannies. At least now it'll be a manageable amount of goo. EDIT: All suggestions on different/better ways to do things are most welcome. Bonus video: How to open a tank cap without a key.
