Deglosser is a nasty mix of chemicals , if it is latex paint light
sanding and proper primer for gloss is all that is needed, If oil paint
sand well and prime in oil. Deglosser is as bad as breathing laquer
thinner from the can, I believe Zylene and Toluene-Tylol are main
components. I won`t use it., definatly on the not to be exposed to list.
