Re: What is good to brush on flag staffs,swords etc. to prevent paint flaking off?
I use brush on varnishes. The gloss one is the Lefranc & Bourgeois gloss varnish for acrylic paintings and the matte ones I use are the Vallejo Polyurethane Matt varnish and occasionally the AK Ultra Matte varnish.
I cover the entire figures to protect them from handling.
