Just received a loco I bought on Ebay, it's an Athearn SW7 in Burlington Northern livery. The loco is used but in very good condition except that a couple of the handgrabs have come adrift. The base of the loco is metal and so are all the handrails and grabs. I'm guessing that the glue used to secure the railing detailing has passed it's "usedby" date and that all the railing detailing will need to be redone. Anyone recommend a good bonding agent for this?
