Polyscale Rust application before cutting and installing the corrigated pieces.

The following link, www.railroad-line.com will take you to a Craftsman Builders site full of details on how-to's. It is free to join, I enjoy the Mike Chamber's Craftsman Corner Forum best of all.

Typical hint: In a nutshell, I dribble alcohol over Testor's Dullcote to create lime scale and hard water deposits on water tanks, tank cars, and plumbing. When combined with a rusty chalk slurry, the effects can be quite effective

Thanks guys!! I'll give your suggestions a try.

OK Dave, I'm drooling.  Even the B-52's would approve of that "tin roof - rusted"!

KD is right, it all looks good. you might try this, too: scrape off some of the rust and black colored chalks into separate cups or other holders. spray the metal with gray primer or rust primer if depending on how rusty you want the roof. dip your brush into a rust paint, then dip into the chalk residue and apply as you like. what you'll get when it dries is rust with texture. you can lightly spray with dullcote if you are going to handle it too much.

Thanks guys! The pictues sure help give me something to aim for. I've got my work cut out for me, but it will be a lot of fun.

Dave that steel buidling with interior lighting is absolutely amazing!!!
