Sanding with a disc sander

Hey guys, I have seen some sanders that look like they are 8″ diameter.
Can you get the panel straight using a disc sander?
Looking for a way to help speed up my work.
What part of the body prep do you guys use disc sanders, at the beginning or after you get your ruff in done?
This guy wants it to be perfectly straight so I worry about using anything but a long block.
Thanks for your input.
Oops, can a mod move this to the proper forum…
u talking like mudhogs???/
:pcorn: Always use a block.
I use an 8″ grinder to remove paint. On the rare occassion that I use fiberglass filler, I will use it to start knocking it down before blocking.
I use a 6″ DA sander for feathering paint edges and finish sanding (with an interface pad).
Otherwise, I only use blocks for body work. I personally don’t use air boards or 8″ DA sanders.
shoot i can block all day with an air grinder it all depends on what the customer is paying for :rofl :rofl :rofl :rofl :rofl mudhogs are hard ta beat but an 8 inch rotary can get ya flatter faster if ya hold ur mouth right:stoned :stoned :stoned

Not for me…
I’ve torn the tendon in my elbow twice, so I have a hard time holding onto vibrating tools for very long. When I use an airboard it can get away from me and I either drop it or gouge the filler…more counterproductive and uncomfortable.
Besides, who doesn’t like the motion of blocking… 😆
Yeah I was talking about the mudhog. I watched the video you made a few mins ago. Seems like it has a large surface to make the panel flat.
I guess I will stick to my blocking.
i like to use a block for final sanding or to check my work against. it takes too long without a DA or mudhog when u have an entire car that needs plastic work.

dont underestimate a mudhog though they can get stuff flat fast what more could a bodyman want plus my arms can only take so much:chair :chair :chairThats what I was looking for… something that I can get 70 80% done and then go over things with a long block with guide coat a few times.

exactly. air tools are great, but they require their own skills or they will end up costing you more time that just straight blocking out of the gate.
I find for what I do I use a cheese grater quite a bit. I’m pretty lousy at spreading bondo in the first place, and I’m a stereo guy slathering up the filler on crazy curvy little parts. grating it down gets you real close right away, and a blocking with 40 grit by hand flattens things out in a hurry.
blocking is cleaner and quieter and gets it straighter but for removing a little excess I have used the da before. …. we block filler by hand. :kofee
I was told to never use a disc sander on large panels because it puts waves so from what i was told its better to use a block on large panels.
