MG Midget and Sprite Technical - Needle scalers

I'm tempted to get one of these to help get all the rust and crud off the bottom of my Fiat Dino (just starting a long, expensive recommissioning).

The youtube videos are impressive but are there any downsides? Can they distort the metal? I'll only be using it on the underside, nothing that shows.

I think they need quite a high air flow capacity compressor, or is it an electric one?

4cfm apparently.

Must check my compressor later.

I've got one and like it but I wouldn't use it on thin sheet metal as it is likely to distort it, good for heavy stuff though. Can you invert the Dino, maybe you could use electrolytic derusting or like a guy in the states who made a large tank and put his whole trailer in it.

Regarding CFM values I always take them with a large pinch of salt as they always seem to use way more air than stated.

I used one on my MGB repairs and it was very effective. As others said it will leave pock marks on thin sheet metal, but its good on chassis members. It also makes one hell of a racket so wear ear defenders. I wouldn't want to use one working on my back under a car. I tipped the MGB over so I could work standing up.

Jeremy...

We used to use them when restoring Tanks...! But on a Fiat Dino... I’d say No No No....! They are harsh and WILL distort the metal.

Elbow grease and time... :-(
