@pennsyfan posted:The only time I tried to weather some thing was the body of a lionel Milk car body that I was using for storage behind a grocery store, and I wanted to rust it out a little bit. Oh, that was a flop. I recently purchased a beep that was sold as Weathered and it didn’t look bad looking at the pictures front view, side view etc. when I got it I’m not too happy with the top view. So I don’t know if I should wet sand with light sand paper to remove the weathering on the roof; or use a chemical. looking for some help here.
My recommendation would be to try "red" Scotch Brite pad to try and remove the darker blotchy areas. I'd do it dry first attempt and keep a damp paper towel handy so you can wipe the area and see if you're making any progress.
The wet sanding could work, but you run the risk IMHO of burning through the red paint on any high spot or corner.
You could add dish detergent if it's stubborn. The Scotch Brite pad if you work from the top (crown) of the roof down should leave you a surface with a little "tooth" that you can go back and apply Pan Pastel or weathering powders to blend it in. If you don't have any Pan Pastels, you could experiment with some lightly diluted acrylic washes in Burnt Umber/Grimy Black. Key word here is lightly diluted, very little craft water based paint, lots of water.
