Respiratory protection while spraying

[stevebrownell]

There are a few posts showing members (and some professional boat restorers) spraying their hulls with standard face masks with various cartridges (for organic vapors, presumably) Given that spraying Interlux Perfection without a positive-pressure system is a very bad idea, what topside paints are being sprayed here, or are people just throwing caution to the wind here and going for it?

I'm strongly leaning towards roll and tip when the time comes, but spraying some parts of my boat would make sense, but the option of spraying Perfection is not on the table, neither is gel coat.

Feedback? Options?
