GSI Creos - Mr. Super Clear UV Cut Flat Spray, Mr. Hobby

What type of mask should be get for using this? I've seen a few of here and ebay, can someone point me in the right direction please?

Hello, what kind of cartridge/filter etc would be best when using a 3M Respirator mask for working with this toxic stuff? Thanks

I can’t seem to get this to build up the tooth everyone talks about on my dolls, am I missing something? Barely get any color down and it’s smudgy.

To fix a doll repaint, can we use a matte varnish or watercolor fixative instead of this product? Unfortunately this doesn't ship to my country.
