Default Sander recommendations?

Anyone want to recommend an electrical orbital sander for doing an entire 22' boat's gel coat inside and out in preparation for new paint? It will include sanding down molded non-skid on most of the deck. There are a lot of options out there between manufacturers and sizes. Anyone have a favorite?

Hey ! I have orbital sander with adjustable speed. In general orbital sander rotate around 12,000 orbits per minute.My model has this property to adjust the speed and I see this a very useful thing, because the quality of the project depends on it, for example going at a slower pace may be useful if you’re working on a particularly tricky area and you want greater control, but a faster pace will obviously enable you to work much more quickly – so having the choice will make the tool much more versatile.I am also pleased that it does not make a lot of dust. I took my BO5041 5-Inch makita orbital sander tool from Bob Smith Tools. That this is not a cheap machine, but it is better to spend more than buying a cheap one once and it will break

All true, BUT the Festool, which is great, is gonna be sneaking up on $500 with tax. You can get a lot of Porter-Cables for that. If this is basically a one time use, makes more sense. Go online and look for woodworking tools. Also, get good quality sandpaper, not the box store junk. I get mine at Klingspor.com

I just wet sanded boat, I used Porter Cable 7424, then tried a 1/4 sheet shaker, then bought harbor freight DA for $32. The stupid Harbor Freight sander did better than Porter Cable.

I am another one for the Festool. Best sander I have ever owned. Connect to a shop vac and there is very little dust. The Rotex version is the way to go. Gives both a circular mode for heavy material removal and the orbital mode for finer finishing.
Several contractors have borrowed it and have said it was a great sander and wanted info on it. They chocked a bit on the price but ended up buying a few.

I have a 5" Bosch that I've yet to kill. Bought it to strip the bottom of a 29'. I've also done a whole set of kitchen cabinets with it, a couple rooms worth pf drywall in my house, the bottom of my 31, the entire mahogany interior of my 31 and many smaller projects. I've had it almost 10 years now, I didn't expect it to make it bast doing the bottom of the first boat. The dust collection system is not good on it, but it does the job.

Lol OP from October 2019 has probably already come and gone on this project but I'll throw my 2 cents in...

I have a Mirka Ceros random orbital with speed adjustment for most of my finish sanding that I use with the Festool dust collector. Also have a Rigid 18V RO sander. I use my IR straight sander a bunch as well for flat surface fairing. Then I have my Fein Mulitmaster for detail work and corners. I also have a little air powered RO that has 2" and 3" pads which works great in tight spaces. I love my cheap WEN 1/2" belt sander. And finally, I use my Dewalt polisher with an 8" 3M Stickum pad on it for cutting material fast. In short, I haven't found one "do-all" sander that would finish a boat.

Festool with Dust collection setup is awesome. I have a dewalt with a hepa setup that works great and a bosch that has a hose adapter to a shop vac. Hell it takes half the pickup bed when we show up to do bottom work.

I like the festool the most and the 500 is worth it.

The Festool will outlast all the Porter Cables you can buy for Festool money.
Also its an easier machine to run. Have both, have stripped entire boat bottoms with both. Wanna buy my Porter Cable?

since this is more of a information subject now that a new guy resurrected it
the 6" mirka is a really good machine, you dont need a fancy dust collection vacuum a shop vac works fine. if you want you can buy a hepa filter for the shop vac
if you have ever used a porter cable compared to the mirka you will never want to pick that portercable up again. the mirka electric machine is smoother than their pnumatics. I own all of them so I am giving good advice here ( or the festool but I find the festool machine bulky and expensive )
sticking with the 6" insures a really wide range of different sandpapers

If air is NOT an option..
A Porter Cable "6" DA Sander" is the way to go.
Dont listen to the haters/Festool cheerleaders
The porter cable is >$300 less and will get the job done just the same.

Use a shop vac with a long hose and connect it right to the tool for a much cleaner job.
