If you just slap por15 on there, it wont work...FYI.

Cool build though.

Well that's a good thing to know for future reference. I had been told that the POR 15 would keep rust from re-forming and coming back once the area had been covered with it. I learn new things on here all the time. And it really is a cool build. Can't wait to see the cab all done and painted to match the bed. It's going to be a really nice looking truck when it's done. ....Joe

Ya, they sell this chemical that you spray on the rust for 15 minutes or so, it changes the actual rust into another material.. Clean and then coat with por 15..... If you use it any other way, it is just like putting a lid on something, it will protect it, but wont stop it from continuing to grow underneath.. That make any sense?

Actually that does make sense. I was told and had thought that the POR 15 was supposed to be air and water tight once applied, which in theory would stop rust from reforming and growing, since air and moisture have to be present for rust to grow.

I was told it has to be topcoated because it isn't UV resistant. As far as I had known, UV rays were the only thing that would keep it from doing it's job. I assume that this other chemical must be some sort of acid especially since it has to be rinsed off with water.

Anyway, I have been told that the POR 15 is an awesome product when used according to the directions. That's why I asked if he was going to use it on this truck. He's doing a lot of work to make it really nice, and as much surface rust as it has I sure don't want to see him have any problems come back later since it's going to be such a sweet ride when he's done.

I have bought some POR 15 for my truck, and hadn't heard about this other chemical. I need to do a little bit of research on it and see how it works before I try to use the POR 15 that I have on my truck. Thanks for the heads up on the other chemical. ...Joe

THey have 3 steps, check their site.
Step 1 = Marine clean.. Its basically a degreaser to get oil and junk off.
Step 2 = Metal ready.. Thats what changes the composition of the rust.
Step 3 = Por 15.

I like it so far, i just dont like the part of spraying it with water. Most people have their truck apart in their garage.. Not like they can move it outside to wash parts of their bare metal down with water ya know.

I've been putting alot of time into this thing lately so I can get it done by May. Over the last few days I've removed the windshield, repaired the rotten dash, and I started fixing the rust in the top corner of the roof. Pictures explain better, so I'll let them do the talking.

Here's the rest for now. I've still got some grinding to do on the welds.

truck is coming along great.. I would use rust Bullet (its one step, compared to POR 15's 3-step) or you could go to a automotive paint stop and buy a bottle of "rust Killer" , a spray bottle of a special chemical that coats, stops, oxidizes, and seals the rust allowing you to primer or paint over it. I ordered my bottle and will pick it up Saturday.
