Ditto! Just shows that restored is often "better than when new"!

Thank you my friend. It is sad how poorly the quality was for a few post war years.

I did get the reinforcement blasted and the back side primed with weld thru primer. Just need to weld it on now.

John long Here is the finished patch welded in along with a few small pin holes welded up. I have not run the reinforcement through the sand blast cabinet yet but as you can see, as soon as I get it cleaned up and the back side primed it will make a good repair and actually be better than new. It is now going to be painted in there.





I did all of this in about 4-5 hours today. That would be pretty expensive for a restoration shop to do but if can convince yourself it is fun, it cost about 4 dollars for a little primer, a little welding gas and a couple of three inch grinding discs.

John long Here is the method I used to make a template of the patch. It is not an origional idea but is very guick, simple, and extremely accurite.

I just taped a piece of posterboard over the cut out area and rubbed the edges with my ,as usual, dirty hands which left a clear mark I could use to cut the template.



After transferring the template to a small piece of 18 gauge, I primed the back of the patch and the inner structure with SEM weld thru primer.

John long Once I got the spot welds out I was disappointed to see the factory assembled the car in bare steel and then painted it. Wonder why most of them rust from the inside out?



Pretty crusty in there. Also, notice that only about half of the spot welds were actually joined.



I cleaned the cowl with a stripping disc and cut out the area I decided absolutly had to be patched. I also used my little spot blaster to clean up the pits that the stripping disc could not reach. This little Speedy Blaster is the berries.

John long I may bore you guys to death but I kind of documented the repair to this cowl. I have about 8 pictures of the process but sometimes I loose my post if it takes to long so I will post this in about 3 segments.

Here is the project. The first thing to do was find the spot welds and center punch them.



The next step was to take a small drill bit and drill a small hole just deep enough to keep the spot weld drill from walking.



As you can see I just started at one end drilling out the spot welds. I would check with a stiff putty knife to make sure they were free and I had not missed any.

1971BB427 That firewall is such a drastic difference, compared to the rust you've found and repaired in the lowest parts of the car! Looks almost like new!
