Years ago I cleaned and repainted the lip
on which the windshield sits when the
windshield was out. Had new windshield installed
After I was done. The guys who had replaced
the windshield before I bought the van used a
Sawzall to remove old glass, I guessed by
the damage on interior pillar trim...and of course
I had rust bubbles on the bottom of the windshield
a year later.

Guys
For info, it is essential, and I mean essential to PRIME the surface of the windshield sealing flange AND the glass with a primer topically applied by 3M's. This allows the urethane to seal both surfaces and prevent water ingress and rust.

Now most of these windshield replacement companies do not do that because of cost and speed!

In fact I ordered one "glass monkey" working for a nationwide chain off the premises for doing crap work on a 2004 T1N van last week ! (Where do they find these animals.????)

We have already had a run in with him over, I can't do this and I can't do that before, and he has earned himself a nickname of Senor No Puedo! (Mr I Can't!)
I spoke to his boss who is a long time friend of mine and I said during the conversation that I know it is hard to find good help, even semi skilled prima donnas, but you can find MEXICANS with a better on the job attitude and skill level than this wanker!
Be careful out there!
There are a lot of Youtube Graduates out there posing as SKILLED People and only there for the paycheck at the end of the week!
Many of them about as useful as tits on a boar!

For those owning an older rust bucket which probably isn't worth lots of repair/windshield removal effort.

All of the the fixes that I did to my 2004 as outlined above are working. The rust and leaks have been held at bay, The Eternabond white tape on the lower section looks good to the point that I don't believe it would be noticed on a white van.

There are a few new rust bubbles inches above the windshield in the OEM white roof that wasn't painted gray. I'll tend to those this spring. Added: I haven't touched them yet. They're still not a problem 20181119.

Apparently I didn't drill my first glass stop hole right down to the plastic sandwich layer. That allowed the crack to start past that crack stop attempt. I drilled a second stop hole and felt the drill drop into the plastic layer.

I learned that the windshield crack UV cure resin repair works very well on fresh cracks. It helped on the old sections, but there was evidence of dirt in the cured resin. Based upon my one experience, drill a stop hole ASAP and deep enough to hit the plastic safety layer. Also apply any crack sealer ASAP. The UV cure stuff seems to work well.

Similar to my windshield repair, I used polyurethane type sealant all around on the rear windows of my 2006.

As an aside. While making a tint cutting template for my rear doors I discovered that my 2006 FL passenger side rear glass was never properly seated into the window recess. That prevented the bedding compound from bonding to the glass. The other window, and both windows on my 2004 are tighter against the metal frame. The resulting leakage caused that window frame to rust out on the inside ledge.

It seems that my external Dicor sealant repair may have been the best solution to the problem.

Great job on the repair, but i might add that when drilling into the first layer of glass you don't want to go through the first layer completely and into the plastic sheet in between. My understanding and experience is that drilling halfway into the first layer of glass and then tapping lightly with a dull punch will create the widest bulls eye that will freeze the crack from going further, once the resin is applied.

I was chasing a crack for over twelve inches before, an inch at a time, because i neglected to apply the resin into the crack, that was about 6 or 7 holes that are in the windshield. But after applying resin the cracking seems to have abated for now.

I had this issue quite bad living close to the ocean, my windshield rusted so bad it cracked!

I was dreading getting it fixed by the bodyshop, $1500 plus windshield and paint, and I was lamenting to my neighbor, and he had his toyota rust out, and he ended up going to the truck bedliner guy. I followed suit, and he did a nice 3" bead in black all the way around, all the rust damage he ground down, and filled all the voids with the bedliner material, and the had the windshield guy replace, cost around $750 out the door with repair, bedliner, and new windshield. It's been about 2 years and still running solid! I guess the material is hot polyurethane, and it's pretty darn bulletproof. I'm contemplating doing the entire van, he quoted me 2K to do the entire thing in a custom color, and you can pick a texture as well.

Question Re: Windshield Rust Hack Job

Hey guys - we recently purchased an 05 T1N 2500, which has some rust around the windshield. Inspired by this thread, we decided to try our hands at an improvement to hopefully slow down the cancer. Currently we are not experiencing any leaking, and I know the windshield was replaced just before we purchased.

I started the project yesterday and the first thing I did differently was to only cut off the rubber flange that protects the gutter around the windshield. The gutter looks like it's in decent shape - not that I could get any tool I currently own in there to grind it out - but I also wanted to leave the rubber gasket around the windshield in tact. _No photos of this, so I hope my description makes sense_

I used a wire brush on a drill. I didn't plan to get to clean metal, I plan to use Rustoleum and then cover with Dicor and Eternabond.

Here's what the bottom of the windshield looked like after I removed the rubber flange and before I started grinding: https://drive.google.com/open?id=1yi...MsvkdQhM2n375b

Here's after grinding: https://drive.google.com/open?id=1DH...3z5vzXK7GyUH2i

I will eventually treat the entire windshield, but wanted to start at the bottom where it's the worst.

What do you guys (& especially Vic, who inspired our project!) think about this plan? -->
Rustoleum on the entire surface under the windshield and everywhere there is exposed rust.
Dicor caulk in the groove.
Eternabond tape starting in the groove and wrapping around the front of the metal under the windshield. Not on the windshield, since I left the rubber gasket in place.

Then, do the same approach on the sides and eventually the top.

Thanks in advance for all of your thoughts and opinions!

Without removing your windshield, you are missing the majority of rust behind the glass on the lip.

A couple of years ago, I had only had a couple of visible bubbles in the paint around the windshield. Due to a truck thrown rock my windshield was cracked. Once the glass was taken out, there was rust around most of the perimeter.

My favorite local body shop ground off the whole lip area down to the metal. He knew that Sprinters were notorious for this same hidden cancer. Several layers of primer, followed by several layers of matching paint, and followed that up with several layers of clear finish.

Removing the glass is the only way to stop what is out of sight and rotting beneath the windshield. Do it once, or be back later to remove the glass the right way.

My experience would show otherwise as to longevity. It will last 5 years ... 6 years ... likely more.

The repair that I outline was done September/October 2012. It is still looking good and holding fine 6 years later.

How many more years do you think some people are going to get out of these old T1N's? The cost and effort of windshield removal, professional rust repair, and re-install of the windshield could exceed the actual value of a T1N.
