I agree that the Perfectionist part is the real challenge.

Painting is not that hard, just have to pay attention to your technique. Youtube is our friend.

As far as media blasting, you can use some self etching primer right after to avoid the flash rust. Just a light coat will do.

'82 GMC ... Yard truck no more!

Question on media blasting.  My truck came back light gray in color according to the pictures from the painter.  I was watching “The one that got away” and their blasted stuff comes back very dark gray,

Why different colors?

How long between blast and paint?  Short time is really hard to do!

I’m going to paint my next project instead of paying…

Thanks,
 Mark

Just a difference in primer color.

I would prime right after media blast to avoid the flash rust you spoke of, especially if your are in a humid environ.

Self etching is designed to adhere to bare metal better than regular primer. Makes a huge diff.

I finally found someone to paint this and deliver it shortly after it gets blasted (hopefully within a day).  I will take some pics of the cab after the media blasting to show you all what it looks like.  Should be about a week or so.  Most of the cab just had (probably multiple layers) of paint on it, but the drivers side floor was a bit rusty.  Hopefully the pics will give people some perspective on what to expect after getting body parts done by a professional place.

Sorry I have no new fun pictures to share on the truck, mostly just stuff for reference when I finally get to go the other way with this.  I attached a picture of a giant snapper that was in my dooryard instead.

So heres some pictures fresh from the blaster, and there were a couple surprises.  The cab had some rust holes above the passenger side door, but otherwise was good.  It kind of baffles me sine the rockers and corners were good.  One of the doors had a dent pulled and was a bit wavy.  I think I did OK.  From the pics you can see the difference between what was rusted and not.  Most of the rust that I noted was on the driver side floor in the cab.  The blaster did not do the inside of the hood between the structure, says that that it could warp the panel.

Fresh as a daisy!

Still can't believe how bad those firewalls look coming out of the factory. Are you going to show is some love?

Weird place to rust above the door! Wonder why?
