Any tip's on painting and weathering a few small bridges from atlas?(truss and deck bridge)
Thanks

Yes! Go to the link in the email
Go to Model Railroad Hobbyist magazine and download the November 2011 edition. In there on page 60, you will find a very good article on kitbashing the Central Valley truss bridge.
Here's the link:

Towards the end of the article, there's a section on weathering. This is about as good information as you get.
