When I replaced my windsheild I ran across a few holes myself. For the most part the frame was solid and the largest hole was about the size of a dime after a good wire wheel cleaning. I used eastwoods rust encapsulator on the bare metal after cleanup, and fiberglass mat to span the holes. after that was sanded to match the rest of the surface I painted fiberglass resin around the entire sealing surface area and sanded smooth when dry. This gave me a better sealing surface for the butyl (sp?) tape. If the holes were any bigger I think I would have looked into other options, but this method has worked well for me in the past for the small holes.

I have good experiance using POR 15 to cover light rust holes on metal. I have also used screen to cover large holes and apply it to make a strong repair. The best repair I made was using the POR 15 putty that comes in a tube. It is some kind of tuff stuff. I would rather use the screen and the POR 15 than fiberglass on this type repair.
Try it sometime on a piece of scrap rusted metal, even with a hole use the screen to bridge the hole and the POR 15 will make it solid once again. You can hit it with a hammer and it stays right where it is supposed to and prevents further rust by sealing it up. jim

For fixing small holes in the windshield top bar, is the POR Patch or the POR Epoxy Putty the way to go? I'm asking because most of the holes are on the bottom, so the filler will have to dry upside down.
One way is a band-aid, the other is the cure

Any holes weaken the structure. Vert.owners pay heed. If you have holes and get any "Cowl shake", it will tear up the Pillar/frame up. Weld them up if anything bigger than a pencil can go thru.

Been there - done that.
Forget about the POR Putty - good for large deep voids only.
For very small holes - POR Patch will work well.

Replaced the corners and header in the '69. It was about a 2-3 hour job after the trim was removed. I used a drill to drill out the spot welds. I took measurements of everything prior to removal of any parts. Then I welded new parts in. I picked up the corners and header at Paragon. They were the cheapest, and had the best customer service. They shipped the parts very quickly, and were willing to work with me. However, the parts are fairly expensive. Also, you have got the rot down pretty low, mine was up high. The problem with the rot being down at the bottom is there is a possibility that you could have to cut the birdcage below the fender line. I hope you do not have to go there, as this will be considerable work.

That is the worst of what I can see with the windshield still in place. The rest of the pillar and birdcage looks fine except for some minor surface rust.
The hole in the picture is 1.5" to 2" long and about 0.25" across. I was hoping to be able to just clean up the area area around the hole and use a welder to replace the missing material.
