Every 3M product I have used has been good. Expensive sometimes, but all have worked well for me.

Jim, I think we've pretty much covered this topic but I just had to make one extra comment. If you are wearing a respirator that is pinching your nose, as Thu, 19 Nov 2009 21:50:38 GMT damian http://groups.yahoo.com/group/multihull_boatbuilder/message/14795 http://groups.yahoo.com/group/multihull_boatbuilder/message/14795 For what it's worth: I have a triton respirator. These were developed for home wood working. They are by far the cheapest option I cold find.

A quick look suggests they have a good product.

It's just a shop vac, some bilge hose, and one of the tyvek hoods similar to the ones for the 3M powered respirators.

When I sand I will typically take a 15 minute break for every 45 minutes of sanding.

Got a pic of the homemade system? The airmate would probably satisfy most of my needs, but I suspect when doing my boat repair the cutting and Thu, 19 Nov 2009 17:32:41 GMT Jim Dory http://groups.yahoo.com/group/multihull_boatbuilder/message/14788 http://groups.yahoo.com/group/multihull_boatbuilder/message/14788 Hajo, Thanks for the info! When I use a respirator, they usually pinch my nose just enough that it is hard to breath through my nostrils - so I end up Thu, 19 Nov 2009 14:50:11 GMT Hajo Smulders http://groups.yahoo.com/group/multihull_boatbuilder/message/14787 http://groups.yahoo.com/group/multihull_boatbuilder/message/14787 if you work with fiberglass for a living i can see the investment in one of the afore mentioned systems.
