Hello,

i'm in progress to restore a 914/6. The car is stripped to bare metall and i found some rust here
and there, but not as much as expected. Fortunately the longitudinals are as well o.k. .

All four fenders are disassembled, so i do not have to worry about them.

That's not the first 914 that i rebuild, but this time i'd like to make it very clean.

Now here's my question: Does anybody has experience with media blasting and the pros
and cons of it ?

many greetings and "luftgekühlte grüsse aus berlin"

Hey Benno,

If you don't do big smooth surfaces, like the hoods or the fenders (they can warp from pressure and heat), you should be fine.
Take it to a place that does cars, not just an industrial blaster.

cheers,

Jeroen

The media blaster here in Portland Oregon uses a plastic bead, I have used him for a number of different things including a 914 hood and there was no warping. I was very pleased with the outcome. One thing it doe's leave the small plastic beads in hard to get to places, comperessed air is a must.
PS: he is a car blaster only.

Cons - I took my rockers to be media blasted. The guy sandblasted instead and warped them.
Pros- He replaced them with 2 new oem outerrockers.

I would be hesitant on large panels. I think your best off doing it by hand. Find a good rust nuetralizer like rust mort, not por15 which cant be painted.

I sandblasted my engine compartment myself (with motor out of the car).....besides making a huge mess in the garage ....I was having to clean sand off of my motor every single time I took it out for a drive....the sand will get into cracks and seems that I didn't know existed.

A medium that is larger than sand would be a better choice, unless you methodically clean and use lots of compressed air to blow out the sand. I'd almost be tempted to put the bare chassis on a trailer and drive around for a while to "vibrate" out the hidden sand if you go that route.

same as the above posts. it'll work great to clean up ther car, but
you need to clean it big time afterwards.
use a industrial vacum cleaner and compressed air.
i had tons of sand coming out of all kinds of hollow areas etc.
it's a mess

Andy,

What did it cost to sandblast your trunks?

i think it was $400.
Got ripped off because the same guy had charged Scott $400 for a complete car earlier.
Ask Brad for more details, i think he knows the guy.

Make sure who ever does it for you has experience in doing car parts. I'm looking for a new rad cradle for my 68 Impala because of this. Wrong pressure and blasting medium can make a mess out of the nicest parts.

I'm thinking about using either talc or walnut shells on my restoration.

The words of wisdom that I got from an industrial blaster is to do a little at a time....

Mueller, the place is right off of 880 and 101. They have been blasting cars for 20+ years. They also happen to be a foundry (if you know what I mean) They can do aluminum casting... get the hubs done.
