Rusty GTE

Post by PSk » Tue Jul 22, 2014 7:25 am

Would it make sense to get the underneath soda blasted or something? Being an Alfisti I strongly believe rust never sleeps and grows so if I see it I get rid of it ...

I hope it can be saved.

I did sodablasting at my 330 and I was very satisfied with the result. Especially when there is rust and undercoat. The undercoat disappeared perfectly at my car. The sodablasted surface was perfect for rust treatment and paint.

Sandblasting worked great on 4247 GT.

Hello Tom,
Not everybody who wears a Ferrari T-schirt can be called an expert.
Well at least your GTE lost some overweight !
saving money on cheap blasting means more money for the paint shop.
good luck with the project.
you´re car was still visible after treatment : a good sign

Couldn't agree more, haven't found a vintage Italian car I can't fit in and drive yet so I guess the diet is working just fine.

As for the shirts, seeing as I made them and one of my good friends did the logo years ago as a tongue-in-cheek version of the Scuderia Ferrari shield. Letters actually say "DGR" which is an acronym for a family name and something my grandfather used for his business.

Back on topic, my painter likes to use a combo of chemical stripping and light sand blasting like we did on Tom's car. Have found that without media blasting of some form a small amount of rust and debris remains in the pitting of the metal and this can cause issues with the paint over time.

Ice-blasting was the treatment, my 2281GT got underneath and I think it was successful. Soda or Sand is a little bit too hard, I think.

Colleague Markus,

Soda means salt , you use it everyday in you're dental office(„Natriumbicarbonat“)

If this would be too hard you're patients should be without teeths, witch opens the market for implants.
.
„Natriumbicarbonat“ reduced the surface tension without damage.

Best

I know, cornelis, but You know, that enamelum is much harder than (rusty) metal.
Salt is very good using it for AirFlow - no doubt at all.
But any rusty (soft) sheet metal to treat with ? I have doubts.

The only problem is, that the Ice-Blaster only blows off the Paint and the other wrong things underneath (f.e. Teroson, Silicone, Sealer etc) the car, wich are not out of metal. To blow the rust off, you will need a salt- or Sand-Blaster. But I liked to see the rusty metal to cut it off much more, than to blast off the rust only.

I've only heard this second hand from a painter and a media blaster that some paint manufacturers will not warrantee paint if the car was soda blasted. Even though it's water soluble, small amounts can seep into the seams and leach out under the fresh paint over time. I think there isn't a perfect way to remove paint and rust. The dry ice method sounds like a good idea, but have not tried it yet.

Soda forms acidic compounds so if it gets trapped, it will eat its way out over time. Paint may flake of.

Sand is heavy and will heat up the metal if the pressure is too high and the blasting angle too big. As a result metal deforms easily. Small amounts are ok where needed, complete paint removal with sand can destroy the sheetmetal completely. I've seen project cars going to crusher after careless blasting.

Mine was blasted with ice and crushed glass.

The floors just don't survive. Moisture goes in the first time the car goes out and stays there. My car has been in dry storage since 1966 and the floors looked perfect but they were paper thin and rusting away along the seams. Three layers of steel with two layers of insulation. Beams were cut with a torch there are moisture trapping overlapping everywhere. It looked nice but we ended up replacing it all.

After looking at Kare´s restoration pics.
it would interest me how his overdrive is fixated on the back side -tunnelside-
a central bolt with a big rubber puck can be seen on SWB and Lusso 4-speed gearboxes.
but no on overdrive units afaik.
those have a resting rubber in the middle and are fixated on each side left and right.
Will place some pics later to be more clear.
Here the central fix. point Kare´s pic.

ciao
