Needle scalers

Is there any place in body work for a needle scaler?. Removing paint,filler,rust?. . I've never used one, and they look like they can beat up the metal or body panels, but not sure since I've never driven one. I've seen some discussions of using them in place of sandblasting. How do they work on cleaning up welded areas (MIG seams)?.
Thanks
David

i would think they would be good for cleaning the flux core wire seams or for cleaning stick welder seams, if its a true GMAW there isn't much slag to remove so i don't think it would be necessary.....it may be good for those spots you can't get a grinder into to clean though like a door pocket or door pillar bottom

Cobra, I have never used these things for body work but as a welder I have used them for years and it would seem to me they are much too powerful for sheet metal and would destroy a panel. Maybe on a frame or other heavier parts they maybe ok but I would very be careful around anything else. Also the imported scalers that are so common are a short stroke design and the better ones like the Ingersolls would probably tear through sheet metal with little effort

They are good for knocking off thick blistering rust on frames before blasting, but keep them away from sheetmetal.

I agree with OldRed. I to see no need for one not un less your going to do other welding jobs. Its a good tool to keep a round.

I have a long barrel dayton that I use to knock off the 5" of mud and tar and petrified skunk innerds and encrusted crudulation from suspension fasteners so I can blow them off with the torch. It leaves a track like an asphalt grinder. precision tool for sure! I think it might be good if you wanted to "texture" a piece of sheetmetal.
hope this helps, mikey

Neddle guns are great on steel or you can use them on the frame to remove rust. I used to use one of them in the Navy of the decks, but would not use on any type of car/truck body.

Thanks guys, I was thinking it would be good to get into tight places, as mentioned in the reply, but sounds like a fairly aggresive tool. I may just get one to satisify my tool fix for the month, and maybe try it on areas of rusted chassis.

I have 4 needle guns I use on a daily basis, as for heavy steel/metal heck yeah it's the only way to go. I use mine primarily for slag removal and heavy rust. Definatly don't use it on sheet metal, it will tear through it..

They are designed for cleaning steel before welding,we've used them for years,also for peening metal such as bearing surfaces on trucks and trailers.

They would kill sheet metal.
