Radiator leak - additive, repair, replace?

I just noticed a leak in my radiator. Haven't had a chance to get it checked out, but I'm seeing a dark stain on the bottom two inches or so of the radiator fins extending all the way across, and a thin layer of radiator fluid that's collected on the plate just below the radiator. Since I'm not able to schlep my bus out of where it's parked for at least another 2 weeks to get it looked at, I'm exploring my options and possible outcomes.

One outcome could very well be replacement, and I'm wondering what a new radiator should run (ballpark) with and without labor for installation.

Another option may be waterglass or some similar additive that seals leaks when it encounters air. I'm a little concerned about the long-term effects an additive might have on the rest of the cooling system. Anyone have any experience or thoughts on this?

Is there any reason why removing the rear heater and associated lengths of hose would have contributed to a leak in the radiator, like maybe it altered the pressure levels in the system somehow?

I need to bring my baby home from Portland to Northern California in a couple of weeks, and will have to address the leak on my way out of town. Thanks for any input and advice. Also, if there's anyone in the Portland area who's got enough know-how to figure out where & why the leak's there, and who'd be willing to take a look, I'd appreciate a tutorial on the cooling system!

Cheers,
Valerie

    The rad, is a very important part ! stop leak stuff ( any type ) is temp. new rad's are mucho denaro. what it probaly needs is to have the tanks ( the parts x2 with no fins ) reatached. Take it out , easy to do, and take it to a rad. shop.( DON'T take it to a garage, they just send it to the same rad. shop and ad on $$ for them selfs) they will pressure test it , boil it out and do any repairs, holes and, or re-atching the tanks. If it's to far gone then a replacement is in order. most rad's can be rebuilt , and should be befor taking it on a road trip if it hase any leaks.
    Good luck
