I'm about to do a bunch of body work on my car, including cutting out rusty sections such as the window channel and front part of the dash.

I don't have a compressor, so I was wondering if it was worth getting an electric metal shear such as the following, of if I should not bother and use the grinding wheel. It seems that this shear would be very handy in cutting out the front section of the dash.

If you will go to a welding supply store they have a 4.5" cutting disk for small grinders they are real thin and work very well. I have a welding and fab. business and use these often.

I second Wayne's suggestion. Metal shears won't work well over irregular surfaces. Or nibblers. The cutting discs go through anything. Quick.

Me too. I used these well before I got a compressor, they are the way to go!

Great. Thanks guys. You just saved me $100.

i also highly recomend the 4 1/2" grinder with cut off wheels. I use it for just about everything

They are great for somestuff. Id use the grinder with thin wheels as mentioned. However, i have used the sheers on other car projects (electric) and they worked really well.
