First, I sanded the cracked area so the epoxy would adhere to the tank better. After applying the epoxy, I let it cure overnight for 12 hours. However, I noticed a spot that I had missed so I applied more quick steel the following morning.
This is the first time I’ve done this so I’m crossing my fingers hoping it works. I’ve seen other videos where people use soldering irons before applying the epoxy however, I did not take that approach because my tank was full of fuel. I did want to risk catching something on fire.
