A time machine in a box for rusty '72 tank
This stuff is just plain awesome. The instructions are clear, the stuff just works great. Couple tips: Before you start, fill the tank with a big jug of white vinegar for a couple days, repositioning the tank every 2x a day to work all surfaces. Flush that out with water & blow out the remaining grey/black rust flakes. This gives the Fertran a cleaner based to start its magic. I used a compressor set to 15PSI as a spark-free method to supply the final curing process with the fresh O2 required to complete the chemical reaction.
