Anyone know the main difference between the electric and air type D/A sanders. I think both are available just wanting to know the pro-con's of each.

It is saves me buying an air compressor and I can get away with using an electric one to strip a car of paint then that is great

 

to be the first to jump on this one, I just asked this same question right here:

https://www.thirdgen.org/techbb2/sho...hreadid=290268

 

Okay just that I read that orbital sanders will leave swirl marks that what lends me to believe the D/A are better?

 

in my understanding all orbital sanders are essentially dual action, as they orbit and spin... pure orbital... not sure if that exists anymore... but hey, I don't know what i'm talking about here.

in reference to your main question... Well i'm still waiting for an answer too, same situation for me

 

if you're stripping the car it really makes no difference how you abrade the finish off the car... you can use a grinder, if it's easier for you, and make sure you only go through the paint...Just keep in mind to not heat the steel.

 

ok. but sanding primer or bondo you probably wouldn't want to use an electric 1/4 sheet sander? with 220 grit or something?

electric orbital ok though? or pure hand block and air tools?

 

Completely block the car by hand for prep while in primer.
No, you would never DA mudwork (or bondo) Hand board the mud only.
I would prep the metal with an air sander, though. (before prime)
much smoother and I would say easier to work with.

 

So looks like it is a go with electric accessories

One question though seeing as I am going to go to bare metal. Probably the best way is to do piece by piece? Say for instance Hood strip the hood, prime it then move onto the next panels.

Is that the way to go about it when I will have about 4hrs of time each day in the morning before I go to work.

The GFX etc.. are made of Fiberglass so no need to worry about them.

Then basically I will have all the parts primed ready for bondo work etc..

Last question though can you get brusable primer? I mean can I brush it on with a paint. This saves me on getting the Air Compressor.

What primer color would you use if the base color is going to be BLACK. I want a nice Dark BLACK shiney Camaro It probably does not matter but better to stay away from teh base color so you can see where you are at when it gets painted?

 

Prime it whatever color you want then use Black sealer.

 

fiberglass gfx? aftermarket? factory is semi rigid plastic right? (either way it's not going to rust...)

I've been looking into roll-on primer and brush on primer for a while.... Search it on google, or autobody.com... there's very little info here on TGO, but in short: it's not well respected by the experts.


huh, I thought DA was what you wanted to use on bondo... learn something new everyday.
an air inline sander can be used on primer and bondo though right? just no electric after stripping old paint?

 

I have an 8 inch sander and an air file I use on mud and bondoglass.The only guys that still do it all by hand are just old school and thats how they like to do it.

 

If u know how to use a DA U can knock filler down with it. But U allways want to block your filler. For bondo on more flat panals i use my 8inch DA than block sand the glaze coat. If u do it by hand blocking it. U cut down the risk of cutting it to low. I think the elce DA will burn out to fast. Get a air one if u have a commpressr that will run it.

 

Up until they went with the aero ground effects they are fiberglass. The Aeros are plastic. Just to clarify

I have a 6in DA Random Orbital air sander that I'm using to take it down to metal. But I've always done mud with a block. That's the way my dad did it and he swears you'll get a better finish, since your doing the work and paying attention to detail.
