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) |

I can't say for sure if you need metal ready or not. I haven't used this or any other product as yet. I have done a little reading and asking about this and other products.
I have heard that Por 15 sometimes does not stick properly to bare metal. It sticks very well to rust. This product and others that are similar work by absorbing moisture. The material fills all the small cracks and pores in the rust. The moisture is absorbed in the Por 15 in the curing process. This prevents the rust from spreading. I read in another pose a recomendation of using Ospho or something else before Por 15. I think this is a mistake. There are other products like Ospho that changes the rust to something else. These materials turn black on contact with the metal. I would be cocerned this may cause some adverse reaction. I also would not use alchol or any solvent in the cleaning. At least you should finish with a water base cleaner. I believe this is spelled out in the manufactures instructions. I purchased another product called Rust Bullet. Haven't used it yet. I have heard it is a good product. Do a google and decide for yourself. Lots of luck on your car. It look a lot better than my project! Mark |
