They guy at the local auto body shop said that metal ready wasn't necessary (probably because he was out of the stuff) before using POR15 as long as I did a good job of grinding all of the rust out.

This doesn't sound correct as I'll never be able to grind and clean up ALL of the rust particles...

However, I've seen the instructions for the Metal Ready stuff, and it sounds like a big mess. Is there another product that's less messier that will do the same thing (assuming I need it)? Rubbing alcohol? (at least that stuff will evaporate on it's own).

Also, I've got areas where I won't be able to wash the metal ready stuff out of if I apply it (center tunnel comes to mind). I can't just spray Metal Ready in there because it's an acid and eventually will destroy the metal- I have to be able to wash the stuff out. So do I just try and coat with POR15 using some sort of 'rag-on-a-pole' method??

New pics of the longs, rust etc:

Since I have a couple of small areas to weld later, can I grind of the POR15 easily (or easily enough) when the time comes to weld those areas? (ie: holes due to rust)

My concern with leaving Metal Ready on without washing it off (depending on how much you use I guess) is that it will 'continue' to etch into the metal. What is this etching process? At what point does it stop? I guess when it's washed off, or evaporates, which would lead me to believe you wouldn't want to saturate an area with the stuff and just leave it to evaporate- especially if it's going to take a couple of days or more to do so.

very good question ... (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)

i can't check on my longs as they're welded shut now, but i can check on my center tunnel as it got the "hurt me plenty" Metal Ready treatment ...
i'll go and check tonight or tomorrow and see if i can see any unusual "pitting" of the surface ...
