Norm,
This is giving me some GREAT ideas to make my rolling stock last longer than me. Thank you for posting this! I'm going to go look for some of this sealant and the rubberized membrane idea under the roof is a great idea (although my 159 will have the metal murphy roof.) Let me make sure Adam Wright sees this as he called me the other night with questions I could not answer about the reefers. Oh - and thanks for keeping the RGS on half the car.
Thanks again!
