Perhaps this will help with my other question:

When sanding paint down to the primer, what grit should I use?
Should it be on an 8-inch grinder?

Sorry RamHemmi, I didn't come back to read the post.

No, you DO NOT sand after the base has been applied.

A big NO on using a "grinder" to EVER touch a car with other than removing paint. An orbital sander, yeah, but a grinder NO.

If any doubt, use hand tools like blocks.

i've been using a grinder with a 125mm disc and 80 grit paper on it to sand my car down to metal/e-coat. It creates some swirlmarks in the metal but is that a problem in any way?

I'll deafinetly agree that grinder sanding is only good for removing paint.

Fenix, the only real problem is the grinder will create heat from the friction. It can also take a body line thin in a second or two. Be very careful anywhere that the disc will be concentrating in one area like on top of body line or edge of a panel.

If you want to invest in one of the best tools ever for auto body and paint work get your self a National Detroit #900 8" orbial sander. You can strip paint with ease and not damage the metal without trying real hard. :)


It is THE plastic filler cutter in my opinion. This tool is about $200.00 (I don't think there are any budget priced ones). I have two, if they were to disappear tomorrow and the price went up to $1000, I would buy one in a minute, that is how valuable they are to my when I make a living at this everyday. I know you don't do this for a living, but after a good DA, a die grinder, an small angle angle die grinder (both very inexpensive ones avaliable) and a 6" orbial finish sander, this is the next tool to buy as far as I am concerned.
