I bought some a few years ago and never had a ton of luck with it, but I never did a great job submersing it either. Back then it was over $30 a gallon, so it has come down a lot.
This thread inspired me to have another go at it.
I found 33" Schedule 40 PVC pipe on Craigslist along with a threaded plug for a total of $5.
I went to Lowes and got a cap, a coupling and some cement for $15.
I ordered another gallon of Evaporust for $16.
So for $36, I'm back in the game. I need to save 3 legs to make it worth my money. I'm excited to give it a go.
