I am getting a D21 ready for paint and stripping the fenders so I took my air gun  to blow out the support ribs on the fenders so that I would not have a blast of dirt come out of the while painting. They were packed solid with yrs of dirt and stone .I took all morning yesterday getting them cleaned out.This tractor was well taken care of and washed regularly but that part gets overlooked on lots of tractors.The steel on the fenders only had one tiny hole where it had started rusting through and I repaired that, but sooner or later it would rust through.Those fenders are really thick and heavy but with that channel type support being open at the top dirt will collect in the as they work. Just to save yourselves rust hole in the future take an air gun and blow up through them a few time a yr ,you will be amazed at how much dirt  comes out.

That is a good tip and another  is to put a straw in your favorite aerosol oil and spray it in the top after you blow the dirt out.  This is a little messy for shine'em and line'em tractors but then again I guess they wouldn't need worry about dirt behind the braces to begin with eh? LOL

Once you have cleaned them, use JB Weld and fill the ends then you don't have to worry about dirt or anything getting in.

If I might suggest a reason not to do this, that will trap at least some moisture inside, and if they aren't sealed up completely they will breath, and the condensation will be worse inside, then the will rust faster, or worse freeze and bulge.  Great idea, just not sure it is the best way.

I was always going to try and fill them up with some kind of gel (naval jelly maybe?) and then weld em shut or seal them some how. Never get around to experimenting with it.

I agree with orange blood on sealing them.  I would not do that.
The fenders on my 175 were filled to the top with compacted soil.  I used a steel rod from a driveway marker to ream them out.  As you can tell, even the braces rotted through (it trapped the moisture)...
