Galvanizing, zinc coating , is definitely a process for rust protection. For bridges, light poles, etc. a hot dip will work. For a car etc... Electrogalvanization will do.
Any way, you can protect STEEL from corrosion very easily these days.

Good luck getting any zinc in the places that matter most.
 
Primer won't protect from rust. Even paint won't last long.

Tons of misleading info in this thread.

The appropriate primer will certainly protect from rust.

Paint will last a very long time when properly applied and cared for.

Seam sealers aren't intended to fill huge gaps like that.

The issue here is that it's pretty much impossible to get any effective coating between the support and skin where moisture collects and doesn't dry easily.
 
It will always be driven! New fenders or old. I was just looking to preserve new fenders. haha
 
Yeah paint properly applied over a good primer will last virtually forever. If the seal doesn't get broken. There is the problem. If it's a boulevard Cruiser paint is fine. My assumption was this vehicle might see off road at some point so I'd. Protect that paint inside the well. Seam seal is made to seal seams not to fill gaps. Primer is primer not top coat. why would you leave bare primer on metal exposed to weather?this one doesn't go on gravel or narrow trails. Should be on display it's so sweet. Different strokes different folks eh.

Interesting never paid any attention to my 79, my newest FJ40. That brace on the early ones is a open channel at the end. It's always been on the area I wash out with a hose to be sure it was clear. Salt does it thing when wet. Dirt holds in moisture. Even is AZ it's not uncommon for the rear sill to rust. My 68 has signs of rust in that location on the right front fender. Need to look into it but figure it has to do with me laying the cruiser on its side back in 1975 and folding the edge over. I straightened it out but guessing it created a small gap around the spot welds. That closed channel will help keeps it cleaner but also make it harder to wash out.:hmm:
 
You could always just sell them. Then someone can put them on their nut n bolt museum build and you could either put the money toward a new tub, buy 3 sets of aftermarket fenders and change them out whenever they start to rust, or just fix your old fenders. Separate the support, fix all the rust, and you still have stock fenders. Then sell the new ones.

They will be lined on the inside with either monster or Upol. It will get primed very well before hand. I mean it will see some winter but not daily driven maybe couple times a month and only on days when cold enough to not have slush on the road.

But then i wouldnt have a set of new OEM fenders haha. The aqulau tub will be in a few year the funds will be slowly set aside for that.

I dont even know what a set of NOS fenders are worth to be honest
 
That was the advantage of buying good used fenders years ago. Not afraid to use them. Remember years ago Mark A posted about a brand new PTO winch still in the crate. While new once you installed it the value went down. Seems funny because at the time believe the seller wanted $1,750. Today see used ones missing parts sell for more than that. If you into this for making money and not as a hobby would have been a good investment. Personally would rather have used then spending money for new and afraid to use them. It was these thinking that caused me to create my own junkyard with the idea parts would be hard to find at some days.

Close. IIRC, it was YOU that made the point about the winch. And they were asking twice the price.

The $1750 was what I was asking in 1993 for that NOS H41 with the 10 spline output. The one I SHOULD have sold you.

:cheers:
 
Agree fully man! I got the OEM's for retail haha. I guess ill blast my old ones and see just how bad they are and decide my plan

Correct on both. Later found a used 16 spline H41 for $300 and then used 19 spline H41 for $500 but that included transfer case with hand brake and LWB drivelines. Years later probably been better off buying all new parts, that way my garage would have had room to move around in instead of full of used parts.:rolleyes:

:cheers:
 
Zinc paint used on bridges will preserve it well enough. Then sell me your old ones cheap so I can fix them up. :D
 
If it's dipped, I imagine it would do a pretty good job.

You try hot dipping a fender like a 40s, and it will be so twisted that it might come a flat sheet.
That 800 degrees is going to relieve the stresses from the cold forming.

I thought when I talked about getting my frame galvanized he said it was 400 degrees. I doubt it would be very good either. Seems like I read about cold galvanizing somewhere. Maybe that would work.
