Rust, rust...finally handled.
So I got under my F-150 for the first time a couple weeks ago (bought it like 3 weeks ago) and realized there was a serious rust build-up on the frame and brackets. So a few days ago I finally got my case of undercoating off Ebay and attacked the issue. After about 3 hours of rust removal and painting, I believe I have hindered its growth as best I can.
My question is, has everyone run into this issue on these trucks? I mean my rear leaf spring shackles/lower control arms looked awful from rust. After coating everything thoroughly with Dupli-Color Undercoating, I hope it's solved as far as damage/weakening to the frame and brackets goes. I strongly suggest Duplicolor Undercoating, by the way. This stuff STICKS. I still can't get it off my arm where I bumped a freshly painted part lol. |
You *SHOULD* have used POR-15.

I see...well my knowledge on the topic was limited, but everyone I had asked said the Dupli-color was great stuff. I will keep this brand in mind for next time, tho. Hopefully I won't need it for awhile lol.

Unless you use a rust converter, it's just going to keep rusting under your brand new undercoating.

I assume you mean these paint/sealers that pre-prep the surface for paint AND stop rust from spreading. I didn't know there were so many steps in this process...thanks for your help. I will know how to proceed next time around :-/

POR 15 is good stuff, if you actually Paint Over Rust with it. Unless you do ton of prep and use all of their products, it won't stick to non rusted surfaces.
Either way, in this case, it sounds like POR 15 would have been good for this job. Anything else will not stop the rust. |

Rust converter?? I was told all I had to do was keep the oxygen off the rust and it would stop spreading...guess that was incorrect. What is a rust converter? Sorry if I seem ignorant, but I am. I have never had such a rusty vehicle before :help:

A rust converter turns rust into a hard black substance. One that comes to mind is Rust-Mort.
With all the time you spent cleaning it up, it would have been a good idea to use it prior to applying the undercoating. It's a thin liquid that can be brushed or sprayed. Some rust converters are thicker, and latex-based. Those are good if you are going to use a conventional paint over it or leave it alone. |

But yea, I haven't heard anything derogatory about POR 15. Until now. The name of the file is perfect Directions for people who don’t read directions : http://www.por15.com/Data%20Sheets/n...directions.pdf Step #3 : 3. You must use Metal-Ready first if you are painting POR15 on new steel, galvanized metal , aluminum, or any smooth metal surface. |
:lol:
Good deal! I haven't seen that one yet. I was figuring if I used it right, it may save me a bit of welding. Huh, maybe that was something else :think: This one, - 7. "If you are perspiring and a bead of sweat drops into the POR-15 can, the paint is ruined and should be thrown out. It won’t stick properly." |
