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: http://www.914world.com/bbs2/index.php?act=...&hl=metal+ready 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) |

depends ... you can brush/spray POR over MR, but if the MR layer is too thick, you'll need to scuff it for the POR to stick right. if you don't do that, the POR will still make a good seal, but it will not stick well to the MR. i have been able to peel of POR in big chunks from a piece of trunk that had too much MR on it ... i don't think it would be a problem in the center tunnel, but then again, i did not use any POR inside the center tunnel at all ... bottomline, if you're gonna put something on top of a thick layer of MR, you have to prep the MR surface first to get some "stick". just like you would prep any other surface for paint ... i just use a spray bottle with a small hose extension ...
