A book I have says, "According to The Keystone, the publication of the Pennsylvania Railroad Technical and Historical Society, stations and other trackside structures were painted PRR Standard Buff with Standard Brown Trim". It then goes on to list the formulas for these colors using Floquil paint. My question is if Floquil (either lacquer or acrylic) can stand up to outdoor conditions or if I should look to another manufacturer (and if so, which colors would you recommend?). Any suggestions are most appreciated. Thanks.
