Remember...I paid extra for this one because it was a "California" Blazer....soooo either you guys do have these problems, or my truck wasn't raised in California.

This is a place that isn't seen....so after blasting it, it gets Zinc...then primer...how else should I finish it?
zinc and 2k would be fine.... maybe throw a little rattlecan black in there on top..
people have been known to take vehicles swimming before!
having been in CA doesn't necessarily qualify as a CA car, plus if it lived on the beach, it's just as bad as living in MI in the winter.
I will take some pics of my 60's CA cars, no rust means no rust.
Where the paint peeled there is some surface rust, but it doesn't go far.
Hmmm, only 3 days to get through this whole thread. No, I won't be going into that much detail on fixing my 78. Having said that, it's only because if a 73-75 shows up I getting it. 
I want full convert and there aren't any in the junk yards to get the swap parts from.
Ryoken? I saw a Quincy today at Northern Tools. $1399 for the 60 gallon. Wife said no. Just as well, it wouldn't have fit in the Honda anyway. The sales guy did say it would be the last one I'd ever have to buy. That still didn't convince the missus.
I bought me some blasting abrasive to clean my hitch there. Is there a special type of sand for the sandblasters? This black stuff isn't something I'd want to blast and use just once every time I clean a part. Or how about an easy way to dry a 50lb bag of sand?
By the way kudos for this thread. Very informative with many pictures.

Silica sand is the most commonly used I believe, and can be used a few times if you can sift it, and keep it dry. it is extremely important to protect your lungs so a simple dust mask dont' cut it here, you really should use a respirator type mask.

This goes out to ryoken and Chief. About the electric DA's,(and DA's in general) As i under stand it, the DA stands for dual action. Meaning you can switch it from from random orbital to a "grinder" that locks the pad in place. Is there any real reason to have this feature as opposed to any random orbital sander? I ask because im looking into the Porter cable unit and it appears to be random orbital only, without the lockout feature that the DA's have. So is all im really interested in the random orbitalness or does it need to be a DA?

dual action is the random orbital motion it makes while in operation, somewhat of a two overlapping circles combined motion...the ones I'm familiar with do not go between single rotary motion, and this dual circular motion...but then my junk is old too.
My DA does not allow a selection....it simply "spins" while doing the random orbit.
The standard random orbit does not spin....I have tried both and the DA runs circles around it....10 times as fast when cutting down paint.

I am NOT a paint guy. But, from time to time I have had to help out in the paint booth when we got behind.
I have used both types. Both of them were air. The true "jitterbug" DA, or orbital sander did a better job.
But the "convertible" one that switched from a grinder to a sander was passable.
It depends on what you are doing. If you are running a paint shop, then you need one of each.
But, if you are doing touchups, minor paint jobs, and looking to save money, then the dual purpose one will probably get you by.
I was sanding the paint on a machine in preparation for painting over the old paint, when I hit a patch of rust.
I stopped the sander, pushed the little tab in, and used it as a grinder to cut down the rusty spot.
Then went back to sanding.
Interesting that the Porter Cable is called a Random Orbit sander and not a DA....I just looked at the box.
Maybe it's not a true DA, but it beats the heck out of the little square Black n Decker orbital sander...I promise you that.

most DA's, at least air DA's have a grind mode.. it's the little knurled round knob above the pad, when turned it will lock the shaft out.. that being said, the porter electrics don't usually have it iirc..
but it's neither here nor there, because it's not a feature I've ever used in a DA.. ever... if i want a rotary cut, i'll break out my 7" makita grinder with grinding discs, or a flatpad... big giant DA on grind mode per se at that point...
it's not really the purpose of that tool... and rotary tools are kinda voodoo for bodywork other than grinders... i've seen people FOCK sh*t up with rotary tools as sanders if you dont know what your doing..
contrary to what anyone says, a standard "jittebug" palmsander random orbital sander of ANY size style will not hold a candle to the cutting power of rotary dual action.. not even a contest...
it is a DA....
Oh...and if you want to be able to use standard sticky discs like the 3M PSA stickits you will want to get the 6" Porter Cable like I got.
That's hugely important to me...
That's hugely important to me...
5" pads bring the ghey...
As an alternative to the sand blaster can a DA be used to sand the paint to metal?
it's by far a more often used method than sandblasting... 50 to 80 grit on a DA and a day of sanding will usually strip, most vehicles..

Ok. I guess what I'm mostly confused to now is the difference in the action of a DA vs. A random orbital. I thought a random orbital was simply a da without the lockout feature that turns it into a "grinder". That's not the case? So there is really 3 things we are talking about here then right? A da, a da with lockout and a random orbital correct?
