Re: 1966 GMC 1000 - Making it Mine!
 

The inside of the panel above the windshield was pretty rough, but no rust through... so I am hoping the Rust Reformer and paint took care of it. I was not prepared to replace that piece... this is not that kind of restoration! :)

The seam sealer was just something from Amazon that was cheap but had good reviews. Same with the primer for these individual repairs.... I will be buying some decent (but inexpensive) Kirker primer when I am ready to spray the whole cab.

Here are links to the seam sealer and primer I used.

Appreciate it!

Tried something new again this weekend in the garage. This time with my Flux Core Welder.

I have 4 holes in each door from old west coast mirrors that were missing when I bought the truck. If I am gonna paint it, I might as well fill in these holes first.

First step was to flap-disk them down to remove the ridge and the paint around them... I then tried something that came up in my Facebook feed last week from Bondo Billy... welding them up with flux core.

This is .030 flux core wire in a cheap Harbor Freight welder on low. It looks pretty ugly at first... and I blew more holes in it practicing... but once you clean and flap-disk them down again... looks better!

These should take body filler WAY better than the original holes. Now to do the rest of them!

One welder told me long ago, "You can be a great welder or you can be a great grinder. But you'll probably never be both". Me, I'm a great grinder. All my welds look like hippo turds :teehee:

You will definitely like having metal in there instead of just packing it full of putty. You can always grind down the excess so don't be afraid to fill it up full. Nice work!

Re: 1966 GMC 1000 - Making it Mine!
 

Would it help if you held a flat piece of heavy copper behind the hole and then weld. I have found that works great for patching holes. Any comments?

Re: 1966 GMC 1000 - Making it Mine!
 

I've seen this method online...I might be able to get a copper plate behind some of these holes, but not all of them. I'll look around for a copper plate.

The short bed I put on my '67 pickup had about a dozen holes in the tops of the bedsides. I used a stick to wedge a penny underneath each hole, and filled the holes with solder. Quick and easy prep for paint!

Re: 1966 GMC 1000 - Making it Mine!
 

Made myself a homemade welding spoon... had some scrap 3/4 inch copper pipe around... just unsoldered it from the other chunk, cleaned up an end, heated it up and smacked it flat with a hammer. Made a little angle for easier positioning...

Couldn't use it for the top holes, just did what I did last time... making sure to protect the glass with a welding blanket.

I was able to get the spoon inside the door for the bottom holes... and it helped.

I had skimmed the other side with putty... but as I was prepping this side, I noticed there are other rust spots under the paint that I will have to address. Now that the holes are filled, time to take the rest of the cab down to bare metal so I can find this hidden rust and treat it!

Re: 1966 GMC 1000 - Making it Mine!
 

To be able to work the cab correctly, I needed to take the bed off. I first tried just some crossed straps from the corners... and it was too much weight and started bending the corners... so I built some frames and c-clamped them to the bed and pulled the bed with my engine crane.

With access to the frame, I figured I should clean it off and treat the rust.

And with the bed out of the way... you can see the damage I wanted to get to on the back of the cab.

I cleaned the frame rails with a wire wheel and sprayed them down with Rust Reformer. I will eventually get the inside of the rails and underneath as well... and they will be painted with satin black.

I started on the back of the cab to see what I was dealing with... particularly around that bad spot. I really like my SCT from Eastwood... but it is SO heavy on vertical surfaces. Also using a sander with 80 grit, and a die grinder with 2" fiber disc.

Got into a lot of body filler where the cab corners had been done. Since I am at it... I might as well take it ALL the way to bare metal to treat and build it back up. It is coming along.
