Nick, Padauk is the worst ever, I think I made a base out of it long ago, I didn't have as much trouble work with purple heart, but it's been over 30 years ago, I really remember the padauk, kind of reminded me of an orange mahogany. Nope never using it again.
Henry, My biggest issue with any mask in the past is finding one big enough. My hat size is 7 7/8, even in junior high I had to get a football helmet from the high school for my big noggin, Junior high had white, high school had red, couldn't hide very well from the coach. 3m used to have an extra large mask like the one I posted, but I can't find it anymore. I tried a full face mask shield and cartridge filters and it was horrible and not close to fitting, maybe my 11 year old grandson could use it. Fit is the key.
