Bud, CYA to me is cyanoacrylic, such as “Super Glue” or “Zap-A-Gap”. I usually use the medium viscosity gap filler when attaching metal to plastic where there is a rougher surface, and the thin watery type to join smooth metals. My latest favorite is “Gorilla Super Glue” since it is cheap, readily available, and has the best cap and most convenient size bottle. The glue gets mostly used up before it goes bad.
Maybe HO is too small to get a good gluing surface, or I have been fortunate to live in more moderate climates, but CYA has worked for me. I don’t like blobs of goo on my delicate etchings, and goo has other undesirable effects on plastic.

I've read much on the steam era list, the majority of who are HO modelers, talking about needing to use a flexible adhesive like Goo to attach the Plano or similar stainless running boards due to different degrees of expansion and contraction of the stainless vs. the plastic roofs. Just wondering if the CYA has flexible characteristics?
