Rust
Hi All
I am about to repair an area over drivers windshield, have cut out the area and need suggestions on how to stop rust between the roof and inside panel. Maybe some Eastwood rust encapsulator using a wand. Would this work? Thanks John |

Re: Rust
hmmm, I just had my windshield replaced and I took the old one out then I primed and painted that whole lip area where the rubber goes. Mine was just a little rusty but luckily it didn't really rot. Looks like you weren't so lucky. Maybe try some bed liner or undercoating on the lip where it will be covered by the rubber????? you'd have to tape it off to ensure it doesn't get where you could see it. On the other hand maybe just paint it, it took 40+ years for it to rot away the first time so in theory you should be good another 40+ lol. The people who did my windshield glued it in. So in theory I would think that would help keep water from getting in there and causing problems. I know they aren't glued in from the factory but the guy said as off 2001 or something they all need to be urethaned in. Hope this helps!

Re: Rust
My plan is to spray everything I can with Ospho. (rust converter)
then weld in new metal and move on. I think a small pump sprayer may do the trick of reaching in deep. Just give it plenty of time to dry before moving on to paint. I typically spray all metal with ospho before scuff, prime, and paint. It should kill any rust still around after cleaning. sSems to help keep bare metal from rusting down here in humid Florida if it has to sit for a while. |

Re: Rust
Spraying phosphoric acid on just converts the top layer, unless you keep spraying for a few hours. If you sand the surface, you'll see the rust is still there. I've actually built a sort of shower stall thing with a pump and drain to spray a chelation rust remover. It worked, but I used PVC pipe and that stuff degrades in the sun. I was picking up bits of PVC for a while.
I suppose the OP doesn't have a blaster to get rid of the rust. |

Re: Rust
I'd be looking very closely at the inner roof (inside the cab) for any signs of rust through, especially where the sun visor's attach, the first cab I had started to do rust repairs on, was very rusty in this area, once I blasted off the paint (portable soda blaster) it was very obvious the amount of rust damage, so, I found another cab and started over.....hope yours isn't too bad......

I don't have any rust thru the inner or outer roof panels. I believe the roof gutter leaked at the windshield just above the gutter caused my rust thru. Before I repair this leak, I plan taking some Eastwood Rust Encapsulator in the spray can with a flexible wand and hope I can kill the rust between the inner and outer roof panels. Take care John |

Re: Rust
I hope that rust encapsulator stuff works out for you, if you could get some self etching primer in there, that might even be a better solution, however, getting a small straw (like what you get on a WD 40 can) in there, might do the trick. if you have removed your visors the holes where they attached will give you a pretty good sized access point. Maybe some very small 1/8" tygon tubing(silicone tubing like what is used on aquariums would get in there and do the job....I have a roll of that 1/8" tubing here at home, if you need some....

Re: Rust
one product that I found that may help you in your fight with Rust, is called
"Jasco-Prep & Prime" I found it at Lowes.... http://www.lowes.com/pd_99271-78-QJPP00717_0__ you want to use gloves with this stuff, as it is a mild phosphoric acid, and will irritate your skin (Ask me how I know) you can use it full strength, or dilute it with water. I used a spray bottle to apply mine, and it worked very well, most of my sheet metal was bare metal most of last year (year round) and I had very little surface(flash) rust to speak of after using this stuff..... word of caution though, use it outside in a well ventilated area, and make sure you flush the excess off your concrete floor, or you'll have stains from the acid left over......another learning experience. good stuff though! I have pictures of the cab after I applied it, but they are at home. I can send you some later, if you want. Have a good one! Ben |
