Hi Folks

I've been reading through these posts. I'm interesting in eliminating the rust I have on the rain channel passenger side of my '71 F250. I haven't heard anyone mention navy jelly as a possible fix. Can it be used

You wouldn't believe I type for a living

I'm asking about Naval Jelly (not sure what navy jelly is). Sheesh!!!

Navy jelly is what happens when they've been at sea for awhile and get shore leave.

I got a buddy that used that stuff on some seam rust. Didn't work. Sand blasting would be better for tight areas.

This is just my own personal opinion, but naval jelly is OK for certain things, like maybe cleaning rust pits on chrome rims, but it's not for removing rust on sheetmetal. There are dozens of products that have come out within the past few years that are much better.

I've used naval jelly for removing rust from pitted sheet metal in combination with steel wool to work it in. It worked very well for me.

Wear rubber gloves!

Thanks for the input, everyone.

I was poking around the rain channels with a sharp object to see the extent of the rust I'm dealing with. I noticed what appears to be dried out caulking pulling away from the cab within the channel. Is this original Ford material or maybe old bondo someone used to hide the rust? Any ideas?

it is the original way ford sealed that area. it could be original or a replacement. if you scrape it out and replace it after you clean all the rust off, ity'll be good as new, unless you need new material.

somebody here will know the brand or atleast type of caulking.

Since the roof panel is spotwelded to the driprails, there's a seam under there.

Here's a view of what you'll see before you scrape out all that seam sealer (looking down on the driprail from above):

...and here's a view after you clean it out:

Since moisture can get in-between the spot welds, Ford used a self-leveling seam sealer in there. After a few decades of drying and cracking though, moisture will get in and rust that area out. If yours is cracked, definitely clean it out and reseal it.

Thanks for that. Yeah, the caulk is brittle and most of it will remain. Hope there is a new material I can work in over the top of it.

Any job worth doing is worth doing correctly! Clean it ALL out and replace it. Don't just smear some sealer down on top of the stuff that's cracked and coming loose. Just use a wire brush attachment in an angle grinder or drill to clean it all out, it won't take long at all.

Thanks for the pix, Keith. I'm pretty familiar with different types of caulking and sealants for concrete work. Know what's recommended for auto use?
