How To: C15a Wire-3 restoration

[Jordan Baker]

Yesterday’s work. Started in on the nose of the truck. The nose is actually in quite nice shape. Years ago when I first got the truck Barry Churcher offered to fix the one headlight bucket for me. His guy did a fantastic job. I’m very much appreciative of that work. Now it’s finally time to finish off some minor metal work then a sandblast, prime and paint. The main fix is to remake the inner shroud and fix a previous poorly done repair by a previous owner. Sadly at some point in its life the shroud was torch cut down making it now unusable. I also need to replace a few of the captive nuts as they were too far rusted. New ones are already on order.

The inner shroud removed.

Does anyone have some drawings or measurements of one? I obviously have some measurements but not for where it was cut down.

Removing the one bad panel from the nose. A rather poorly done previous repair was the main reason. Globs and globs of brazing with an ugly seam across a flat panel is not a repair. The air hammer made quick work of the wartime spot welds. I also picked up new steel today for making a replacement panel and the air shroud.

Yesterday I cutout and made up the replacement nose floor panel. I also picked up the nose, hood, grill and brush bar from the sandblasters. I started painting the POR15 on the nose. With all the seams, I decided to hand paint so I could ensure that POR got into them. Spraying would have been difficult trying to fit my sprayer in.

Hi Jordan


My experience, several years ago, with POR15 as a base coat was that had to have the special Tie Coat primer used over it to get primer and top coat to stick. But now when I check the Por15 web site https://www.por15.com/All-Products-Category does not show it. So I'm left to wonder if they have changed product? Will watch with interest how you proceed.


Cheers Phil

They still make it. Just changed names to High Build Primer. Still uses the same part number.

I think POR have renamed several of their products recently:
Tie Coat Primer became High Build Primer
Chassis Coat became Top Coat DTM Chassis Black
Prep and Ready became Metal Prep
Maybe more name changes to confuse me....

Often a name change will be a way to raise prices. Old product will remain for a short while at the lower price until exhausted while the new product sits there for a bit more money.

Personally, I have never use the tie primer. I catch the paint when it is slightly tacky, and I get good adhesion as well as a transfer of some of the hardening properties. But it is very dependant on timing...too early and you get cracking/crazing on the new paint.
