Reciprocating scraper - needle scaler or chisel?

[Chipper]

Having a lovely time scraping off 40+yr old rubberised undercoat off my car. The well is open so means doing inside of wing, the inner wing, and front panels.
So I was thinking maybe adapting a thin flexy scraper blade to one of the weapons in the title, might save some of the aches and sweariness, and speed things up. What would you pick?
Wondered if the chisel might have too much movement or whatever.

I used a snap on air gasket scraper to strip the underseal from shells.
I bought a Bosch electric one but never got round to trying it.

Thanks guys, off to do some searching, cheers.

Some time ago I bought a cheap Lidl electric chisel thing meant - I think - for paint stripping. Cost about £15.

Found it was absolutely perfect for stripping underseal and seam sealer.

I've also used it as a chisel for chasing walls for wiring, but only in plaster and insulating blocks. Air chisel or SDS drill for concrete blocks.

For such a cheap tool not only does it do the job perfectly it is lasting amazingly well given the abuse it gets.

I think eldest has some photos of it in use. I'll try to get them off him when he comes home for Christmas, assuming he actually gets here given the weather.

Cheers, that sounds interesting ... especially with the price... If it only lasted while I do the car it'd be fine. I'm back to the air chisel/hammer or scaler idea because of cost, though the other things do look very good.

Forgot about this - made a scraper widget for an air hammer by chopping a chisel bit, and a DIY scraper, melting them together.
Worked great at chipping off a gallon of bog covering some dodgy old repairs on my car, without damaging the metal. Making another one with a bit more flex for attacking the old rubbery underseal on my motor:
