Someone wrote a few weeks ago, either in here or the Armor hooch, a question about a source for fine brass mesh for intake screens, radiators, etc..
I couldn't remember the brand-name for my source, but i finally stumbled across the package when I was going through some boxes in the War Room..
It's "Paragonn", although it's copper, not brass, as I initially thought..
I got it at Hobby Lobby (it's located back with the scrap-booking materials) and runs around $12.00 (unless you use the 40% off coupon) for a 16 x 25-inch sheet... That's enough for almost a lifetime-supply of radiator and intake screens in 1/48 and 1/32-35 scale..
