1956 International Harvester - Paint codes and WEEKS of sanding continues!

Even though the '56 IH 4x4 went into primer over a month ago, it's taken many many hours of sanding, filling and re-sanding to get it close to paint. This is the time not to scrimp on time and effort: everything you miss now shows BADLY in the final product!


^If you look quickly, you'd think this photo - and the first one in my last post - was one and the same. But you'd be wrong.....by about 30 hours of block sanding and re-priming between the two!


^ As we're getting closer to painting this thing, it was time to find the 
paint code and order up some paint. For better or worse, today we have all 
the worlds information at our fingertips.  And all doomsday internet talk aside, 
it sure makes it easy to find obscure things like paint chips and mix codes for 60 year old trucks! 



^ Rough patches near the new box floor - even if we spray bed liner it has to be right!


^ Tiny little blemishes to some - major issues to me!


^ Inside the door edges were even beat up!


^ Blocking out the tops of the fenders - for the 3rd time!



^ Rear fenders where so rough - just little bits left to do...



^ Hood is near perfect



^ The front of the box, against the cab may not show much, but it still needs to be finished!


^ Lots of smaller pieces to get to as well 



      Trying my best to get it painted this month - but to rush it now would be a BIG mistake!
               Patience - and hard work - is the key to a great paint job and restoration.

Sanding high-build primer: Hour 25

Continuing  on sanding the first coat of high build, adding a little glaze putty to remaining imperfections and catching anything that stands out....



After the first sanding of the first primer coat, there's always a few spots that need a little more attention than the primer can provide. In these cases a very thin skin of "Glaze" is used. It's somewhere between filler and filler-primer and meant to bring the body to the 99% stage.





This is the time to catch anything hidden or not quite right. For example, in the inside corner of the door I saw a little bubble. I thought it was some sealer or a weld, so I hit it with some coarse paper and found it was a tiny rust hole. So I ground it out, cleaned it up and treated it with Metal Prep, my go-to rust treatment. Next time around I'll fill it with some metal-based filler and smooth it all out.


Another issue I caught where a couple of hairline cracks on the inside the door edge, near the vent window frame. Caused by so-many years of the door flexing at the vent window opening. As the window was opened and closed the door frame flexed and eventual cracked. Had I not caught it it would have cracked through the paint and continue to worsen. To repair it after paint would have meant having to repair and repaint the entire door again.





It also happened lower down on the door, where the lower part 
of the vent window frame attached to the inner door shell.


Oddly, there was also this damage to the inner door jamb. It was hard to see until I blocked out the primer and it's almost the same on both doors! 
I can't figure how the hell it would have been damaged either...maybe the owners can tell me! 



This is how she looked tonight. Next time in I'll repair those last little bits and get a second, final coat of high-build on it. At this stage I'd say I'm about 15-20 hours from paint!




Except for......

A friend of the project found this tailgate from who knows where. It came sandblasted and was nearly rust free. It's also VERY solid - much more so than the one that same with this truck....


                               But, can you spell: "R-O-U-G-H??!!!". Well you're gonna learn!

The attachment corners are so badly damaged it looks as though, instead of unbolting the trunions, they just ripped it from the truck - red neck style!


The other side was just the same. That'll take hours each to straighten, weld, true and grind.

The bottom rolled end is all smashed in. Even if I can figure out how to repair that, it'll take many more ours. Might be easier to find a similar diameter pipe, cut the bottom esde off and weld the pipe on to emulate it!



Then, if by some miracle I can get all that done, I'll remove this 1968 plate 
- that was unceremoniously drilled and bolted to the tailgate -  and fill the holes behind it.


Stay tuned for more exciting times ahead as the truck gets color and we figure out how to repair this tailgate. Personally I'm praying for a 'new' tailgate to show up courtesy of one of the thousands of readers the blog has (I know,... I don't believe it either, but that's according to the Google-stats!)

Block-sanding weekend


I worked in my Dads body shop from about 1975 to 1982 and nothing was block sanded back then. We used a heavy rad-oxide lacquer based primer and just sanded it with a piece of folded sandpaper in the palm of the hand. Back then paint went with lots of "orange-peel and no clear - so it wasn't as shiny and therefore didn't show as much. People where less picky then too because the paint that came out of the factory wasn't as nice as it is now.

No automatic alt text available.

But now-a-day, panels are expected to be laser straight and shiny, so we block sand high-build primer - with long blocks - to ensure everything is straight. It makes a huge difference, but it's also a huge undertaking.

Image may contain: one or more people

Next weekend I'll finish up this first round of block sanding, address any larger imperfections, then spray a final coat of high build. This final layer will be final sanded to 400 wet for sealer and paint. Which is to say we might have this thing in paint sometime in April... (no promises of course! ;))

Stay tuned!

PRIMER TIME!!!

After many hundreds of hours on body work, the International S120 is finally getting a coat of high-build primer! The inside of the box is still a little on the rough side, but the outsides are 98% so it was time to get it primed.

First things first - clean up: anoterh 4+ hours were spent getting everything put away, sweeping up all the filler, vacuuming up all the filler dust and then blowing out every nook and crevice (twice).





And with everything cleaned up, it was finally time to buy and mix up the primer. 
At $200 a gallon I certainly don't want to waste any of it!


Mad Scientist at work!




First coat - you don't realize how much surface area there is on a vehicle until 
you have to go over every inch of it - both inside and out.


I use a metal gravity feed gun for primer:






Inners too!




Phew!!!  SIX solid hours of priming makes for one sore arm!! 
Although its a milestone, it only means the start of the (first) block-sanding stage....
