 Posted: Wed Oct 22, 2003 1:16 pm Post subject: Rust Proofing New Rockers and Heater Channels |
 |
|
| The passenger side of my Ghia is all cut open and ready for the new rockers, reinforcement rails, heater channels, etc. The new floor pans are now in. My question is, Should I rust proof the inside of all these new metal components before they are welded in their new home? I have read other posts where guys are trying to spray POR-15 on the inside of their heat channels and rockers. I have a chance now to spray on the POR-15 to the parts before they are welded in. Is POR-15 the best for this? Is this a good Idea? Is it really necessary or is it over kill? Has anyone done this? Can the parts be welded in if they have a coat of POR-15 on them? What do you guys think? --- Tony |

1. POR-15 is a great product. Used as directed, it works excellent. However, prepping for it isn't exactly easy. There are other products, like "Rust Bullet" that are very similar, and require less prep. (More on that in a moment.)
2. Yes! KG rockers and heat channels are VERY rust prone.
3. Necessary if you plan to drive on non-sunny/dry days.
4. Not me. (More to come.)
5. No. POR-15 is non-conductive.
6. (Here's the moment.  ) There's a product called PICKLEX-20 that claims to have all the rust protection of POR-15, requires almost no prep, and is weldable!
PICKLEX sprays easily, like water. In fact, it comes in a spray bottle. It dries quickly, doesn't stain the skin, and best of all, it is weldable. And it costs less! 
When I got it, I sprayed it onto some rusty metal and set it outside my garage. 4 months later, it appears to have significantly inhibited new rust, but not stopped it completely. Perhaps that was because I just sprayed after a couple swipes with a wire brush.
I'm doing some testing with Rust Bullet & Picklex, on a badly rusted pc I cut off the car, and some sheet metal stock that I let surface rust. This time, I wire brushed the pcs as clean as I could prior to application. They're outside now, but it has only rained once or twice since. I took pictures, so after a little more bad weather, I'll post the results.
It is obvious to me that the Rust Bullet treated portions won't rust again, as RB is a paint-like coating, much like POR-15. The Picklex becomes invisible, so only time will tell.
If you do a search on "Rust Bullet" and "PICKLEX", you'll find links to their websites.

Thank you for the information. I looked them up on the web and here are the sites I found with information:
http://www.stoprust.net/
http://www.picklex.com/
http://www.picklex.com/Process.htm
www.stoprust.net claim that rust bullet is better than POR-15, however, they are both non-conductive and therefore non weldable. This would not work for me since the parts are new and they need to be welded in place. I guess that once they are welded in, I can try to coat them on the inside with either POR-15 or Rust Bullet. I know others have tried to do this. My other option would be to use Picklex on the new parts before they are welded in place. Like you mentioned, they do claim that it is weldeable. This is great for me since I can coat the parts with Picklex before they are welded in place. This means that they will be protected from rust in their new home. However, is picklex all by itself enough? From the web sites I read, most powder coat on top of the picklex or apply some kind of "paint" for further protection. So, if that's the case, I am back at square one, still having to coat the inside of the parts after they are welded in place. I am hoping that picklex is enough all by itself, and will continue to look into it. If anyone knows for sure, please post it up. Also, which is better, POR-15 or Rust Bullet? Same? Why? |

I found some more comments on Picklex 20. Check out what Holloweenking has to say about the topic.

Do you guys agree? From what I have been reading, I think I may use POR-15 on the new parts and mask off the areas that will be welded. Then when it is all welded in place, I will only have small areas to go back and cover with POR-15. Does this sound like a good plan? |

Thanks for the further info. I'll have to add a Metal Ready pc to my experiment. 
I think your plan of attack sounds very reasonable.
Good luck!
