HA!With 11 bottoms to do I might suggest changing the name of your boat!![]()
Thanks I’ve been looking for a good screen like thatI have a Bosch Orbital Sander purchased from Lowes.
It has a vacuum hose connection that sucks most of the dust to a vacuum with a HEPA filter Bag.
Bottom jobs need to have some grain sanded into the existing paint so that the fresh paint will adhere. It does this either chemically of physically. You need to create a roughed surface for a physical bond.
I have used 80 grit sand paper. It is a job but it can be done. You have to throw the paper away constantly to keep it fresh and still working. You want to suck up as much of the dust you create as possible.
That is where a "sanding disk" on an orbital sander comes into play. Not just any disk. I saw this "Screen" on a youtube video of a guy in Europe, Sweden I think, sanding his fiberglass project with a sanding screen. They were lasting him much longer then the sanding disks do on my sander.
Here is the product. Mirka 9A-241-080 6-Inch 80 Grit Mesh Abrasive Dust Free Sanding Discs, Box of 50 Discs They are available from Amazon.

I plan on giving them a try on my next project. They may be helpful to you.
Yep, a few will need scraping and the rest need to be roughed up for paint. Thanks!I had several layers of old flaky bottom paint. i found it faster to scrape it with a 4" razor scraper then sand. i am just sanding with 60 grit on a Wal-Mart special $20 orbital.
Oh also—is that the ~$300 model? Saw it come up in search. Thanks—I have a Bosch Orbital Sander purchased from Lowes.

Absolutely. I’ve used them and they’re way better for bottom paint than paper.That is where a "sanding disk" on an orbital sander comes into play. Not just any disk.

They use a lot of air so you need a pretty substantial compressor, no toys.If you've really got 11 boats to do, get a orbital sander that runs on compressed air. Much lighter, doesn't overheat, All the pros I used to work near/with used them. Sorry, can't tell you a model anymore. I own the Bosch that @jssailem mentions above. Very nice unit, but if I was doing 11 boats - I'd go get a tool that runs on compressed air.
