Is this intake manifold salvageable?

I have a sb aluminum intake that seems to have been underwater or have developed an antifreeze leak on a previous motor. It looks like the leak occurred at one of the water passages and perhaps hydrolocked the engine; then sat there like that until someone got around and disassembled it.
The inside of the runners develops a grainy white growth,even after it was removed/cleaned. The intake manifold face at the waterpassage is coroded and dimpled for several inches. I know that someone is going to say post a picture. I just reformatted the computer and haven't got the picture size thing figured out yet.
Can the intake face be sealed with a product and given an epoxy skim or something? Suggestions? other than get a new intake. I am just looking for a short term fix for a year or so, until the new engine is ready.
Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen!
Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!

Like was said... bead blast it inside and out then skin the mating surface with JB Weld... draw file it smooth

I spent some time doing a cleanup to see how bad things really were. I am going to glass bead (because I can), and I was going to paint it anyway (engine color). The re-occuring growth got me thinking that it needed to be sealed. I found a nice 1974, 50,000 mile temporary 360 for the time being to try and keep the car mobile.
Thanks for the suggestions. I just wasn't sure if the jb weld would hold if it was porous or compromised aluminum.

I got one off of ebay like that once. In the pics it looked brand new (SB dual plane M1), when I pulled it out of the box I found what you described on the underside, my guess was very old antifreeze that turned acidic. No experience with the fixes others mentioned, but if you like the manifold I took mine to a good head rebuilder. He bead blasted it, shot in some new aluminum with a tig welder and resurfaced the mating surfaces. Wasn't a cheap fix, but cost less than a new intake.
Good luck!
