I use a garnet abrasive that is made for water jet machines. 80HPA made by Barton. Works well, or another is coal slag type like Black Beauty. In general, recalling earlier comments above, you want med to fine media (smaller hammers) and lower air pressure (lighter hits of the hammers) while holding the nozzle at an angle (less impact). When blasting inner doors, inner structures for hoods, trunk lids, etc, block off openings that you don't hit open areas and get the issues I showed above.


I wouldn't recommend soda, it will change PH of the metal where Epoxy doesn't have it's bite anymore, and may pull off in sheets, or sand as most also contain caustic salts, not something you want impaled into your sheet metal.

I used black diamond media one time on tractor rims. Maybe you know of a different type, but it was soo aggressive that I ended up going back over with silica sand to smooth them out.

I usually use Black Beauty on most everything. If I see it's overly aggressive (if that's really possible) I'd blend in some of the glass bead I keep on hand. Or even better - blend in some of the used B.B. to take the edge off the new . But this will add time to the job too. 8-(

Perhaps back away - increase the distance from the tip to the work piece? And work on an angle with lower PSI?
Just thinking out loud.. LOL.

What 40? I sold it.

You know where liars go don't you? ....................................Yep, Therapy

He'll have to start a thread called, "CUMMINS & GOIN'S"

So we've been blocking out epoxy primer, it sure is nice to be able to rotate the car where you need it instead of sanding upside down on the bottoms of drip rails.





But then you walk past the Driver's A pillar and see holes that shouldn't be there.








I don't know how I've missed this before. We did have this same repair done to the other side, I guess with the roof damage confined to that same side I must have not thought this side was suspect. Goes to show, check ALL problem areas, especially if issues show on one side.











Inside the hole has a minimal amount of surface rust, especially for 64 years old. Safe to say the damage was caused by water/dirt accumulation between the center structure (the one we're remaking) and the outer skin. Oh well, it's been a while since I've had a back up and punt moment. Glad this was found before the green kandy went on.


Starting to make the new replacement for the inside, using 14 gauge cold rolled steel.

Quite a bit if stretch added for the part to match the original..








Rough shaped on the MH19, tuned up a bit with body hammers, punches used as anvils, and various other implements of destruction. Trimmed and fitted:











All ready for welding. Meanwhile, Mike has been working on the pointy end of the arrow, here stretching an inside corner to better fit the housing....

And adding holes for the plug welds....

Good catch on the little rust hole, Robert! Your attention to detail is inspiring, and amazing!

The arrow's looking sweet, too! Thanks for your great posts.

I love how you guys can just fab up any type of panel that you need.

Nice find. You use a lot of hammers. I guess you aren't a mechanic then?

What I really like is you take the time to make an exact or as near as perfect reflection of a patch as you can even though it is an inner structure that gets covered up and may never be seen again. That is impressive.

It's a sickness I tell you....

Here's what we did for the gutter system that sits above/around the cowl vents to keep your feet dry. Typically leaves collect inside the cowl and wreak havoc, starting the rust process in short order, and this is another "hidden from view" repair.


the fab process for the internal gutter.

Cut out:



Bent up:



Trimmed and fitted:



Welded up, welds dressed:



Comparison:





All parts welded in place:




And then all covered up for no one to see:




So I don't know if its OCD or just anal retentive nature in trying to do it right.. Maybe I need professional help..

If your going to do it why not do it right At least you know its right

Sometimes it's crazy how much work I do to something and then I miss a spot that is obvious as ever. Glad you found it and I'm pretty sure it's in capable hands LOL
