Hi Simon,

And therein lies the problem. Some sources indicate that enamel paints require different filters to acrylic paints. Some say the P2 filters are the go for acrylics, others say P2/Ax.

The mask I use has replaceable cartridges, but which to get?

I understand the UK use FFP1 through FFP3 as the ratings, of course Oz has it's own way
