My local Canadian Tire didn't have any Evaporust so I picked up Metal Rescue Rust Remover Bath (http://www.canadiantire.ca/en/pdp/metal-rescue-rust-remover-bath-3-78-liters-0477920p.html#.Vug9QeIrJaR).
I had great prior experiences with EvapoRust, but wasn't quite happy with the Metal Rescue. I'll post some pictures later, but basically I dipped a lockdown bar receiver which was really badly rusted. I had a little part of it sticking out of the liquid for a couple hours (I hadn't noticed the container had shifted) and after that I reset it properly.
It did an alright job of removing the rust over 24H (although I have a feeling EvapoRust would have done better), but I have a clear line that remained where the bar was sticking out. It looks like it kind of attacked the metal a bit too.
I had used EvapoRust to dip portions of large metal parts before and was amazed at how it left everything but the rust intact and I never wouldn't notice anything going on at the liquid-air transition.
Has anybody used the Metal Rescue here?
As I was writing this I had this video running of a guy in Australia who compares both these products on similar samples, with the Rust Bucket product as well.
After 1 hour, the Metal Rescue has virtually no results, EvapoRust does pretty good, and Rust Bucket does even better than that and is the cheapest of the three.
4 days later, the Metal Rescue has crazy flash rusting, none for the other guys. I did get some flash rusting from the Metal Rescue as well.
Again, sorry for updating as I watch, but it seems that the guy is a distributor for the Rust Bucket, so it should be pointed out. Looks pretty legit anyway.
