I have used Humbrol paints in the past. I liked them and had no problem with them, but I hated pouring the paint out of those little tins, always made a mess
When I was stationed in England, I used to frequent a hobby shop in Oxford and I bought many Humbrol paints.
When I came back to the States in '87, All my tins came with me, but alas, that was 30 years ago and all those paints are looong gone
Cheers, Ian
