Polyester dress lining material is exactly what Sig Koverall is. The properties are well known.

There is a site, for which I have lost the link, which shows which paints are compatible over or under other paints. I'll post the link as soon as I find it again. Everything is compatible with Nitrate, but you have to be careful what you put over Butyrate and Butyrate is known to blister many finishes over time.

Where do you pick up Fab Tac?
