I also live by a small salt pond...

dude are you serious? Battery hold downs are your friend...
I live on a sandbar, 13miles out in the water, the land is only 4 miles wide, we have a SLIGHT issue with rust/salt here...
We use alum for a reason on boats... just sayin.

I am going to give one of these a shot (just orederd it) Ill post up here when it comes in.
I live by a small salt water pond too. (My town made the news when a fully loaded commercial jet plane crashed on my block in 2001 and killed my neighbors.) That area is between a salt water bay and the Atlantic. We also suffer with rust and corrosion issues, so I know where you are coming from. Many of us also have boats out here, so I also know where you are coming from there too. And we all 4 wheel in the ocean. I have never liked Aluminum, but like I said, that is just my $.02.
As far as brass, a little acid from someone's battery, a little flux, a little heat and a little solder can get you back to playing in less than 10 minutes, and it lasts forever. Brass is also more ductile, meaning it has less of a desire to crack when bent. Brass undergoes "plastic deformation", but it usually holds water. When you 4 wheel, things sometimes just pop up. Some of those things seem to look for radiators. I like knowing my rad can bend and not break, and I like to know it can be repaired easily.
There are lotsa' people here who know more about Landcruisers than I do. I respect that. It is just that I have wrenched for the last 25 years plus, and I have made the Aluminum radiator mistake. I respect those who want to use Aluminum. It is just that unles you come prepared with a 800 degree F torch and Alumiweld/Duraweld (not a common product that people would know about), you will have issues fixing a rad on the trail or on the way to work. On the other hand, brass rads require lower temp torches to melt a solder mix and flux that you can easily get anywhere including Radio Schlock.
Knowing I can get a torch, flux, and solder at Radio Schlock or at the local dollar store in order to save a day of wheeling is priceless.
Once again, my $0.02, and your mileage will vary. I am not looking to disrespect anyone here. I respect all the Aluminum guys. Please also respect my viewpoints.
