FERTAN - Tank Restoration Kit

I’ve use the fertan tank kit on an 1974 R90/6 that was sitting in a barn for 35 years. I was a bit discouraged discovering that about 1/8 of pure rust was covering the entire insides of the tank. Here’s the steps I’ve done to completely bring the tanks as new: 1-solvents to clean the old fuel and crust 2-I poured the fertan solvant with 100 drywall screw and shook it for half an hour in every possible angles 3-remove the screws with a magnetized rod And pressure washed the tank 4-used fertan rust remover for as per instructions, then pressure rinced again 5-used fertan rust converter as prescribed, rinced and dried fully 6-build a setup using a cardboard box to which I ductTapped a fan in preparation for the final step (epoxy) 7- mixed the epoxy 2 component for several minutes until super fluid 8- poured the fertan epoxy mix in the fully dryer tank and moved in every directions to ensure full coverage. 9- taped the fan setup so air can flow through the filler opening and had it run for 5 hours. 10- let the tank dry for a day. Voila

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.
