colorsanding

[pilotsailing]

I am going to purchase an orbital sander for colorsanding. which one would be better. the airvantage 6 inch or the hutchins waterbug wet sander. the hutchins costs about $100 more but I'm wondering if the wet sanding option might help in some way. this will be my first time colorsanding.

Go with the Airvantage 6" with a 3/32" Thro.

You can lightly mist a panel and use the AirVantage so there's no point in all that water.

Take Care,

I agree. I don't really understand the point of the waterbug. I have one of the orbital waterbug II's and not the random orbit waterbug III and I've never used it simply because it makes such a mess and isn't necessary anyway now that we have 3M's 260L microfinishing film discs which can be used either wet or dry.

It's best to use finishing film dry but I'll admit from time to time I've used it wet on paint that tended to load the paper. In this case a misting bottle is a much better solution than any other I've tried.

I think the whole idea is a throw back to the old days of using sheets of wet or dry paper on a jitterbug sander for machine wet sanding. 260L changed all of that so I see little point to a wet machine sander today.

I had the Waterbug here for a test run and used it on one job and never picked it up again. Too much mess on the car, on the floor and on me.

dry sanding is the way to go, less mess to clean up :)

Hi, there both ok. I use a 6" model made by craftsman which is available
at sears, it costs around $100.00 or so spins up to 12500 rpm max and has low
cfm requirements.

If your looking to colorsand with the da, use a Stickit 2 disk from 3m on the
sander and the mirka abralon foam backed sanding discs.

No mess no fuss, I think you will be very pleased with the results.

Best regards.... X

A couple of mistakes here X... Stickit is a glue on disk Hook-It or hook and loop is a velcro-type disk and Hook-it II is velcro with the hooks and loops reversed. You can't use Abralon on a Hook-It II disk only on standard hook and loop. You will also want a random orbital sander with a tight throw (3/32" is best) so that your sanding isn't vibrating on your finished paint job and it won't load up the fine paper too quickly or generate hook patten in the painted surface. I like the 10,000 RPM sanders because they usually have a little more power and you end up slowing them down about half speed anyway.

Len, your right, I meant to say Hookit, had stickit on the brain .. lol.

My da is a random orbital type, from memory its variable up to 12500 rpm.

When color sanding with the Mirka discs I typically run it pretty slow, seems
to work very well !

It sure beats doing that grunt work by hand. With the sander I seem to get
a better overall results than using a soft block with wet or dry paper.

Thanks .. X

If I had to continue to color sand by hand I'd be retired by now.
