Noch 60873 Modellwasser Artificial Water Problem

Rob writes:

“I’ve used the Noch Model Water product and after 3 days, it has dried cloudy as opposed to clear. I applied it in one pour, to a depth up to about 3mm and left it outside under an awning (with no direct sunlight, wind or rain). Can anyone tell me what I have done wrong? Can anyone tell me how to fix it (other than to rip it out and try again)? Thanks in advance.”

Will Weathering Affect The Resale Price Of Trains?

Ian asks:

“I probably have another year or 2 before I seriously start thinning out my train collection. I have weathered 17 engines over time and wondered if has increased or decreased their resale value. I think I’ve done a good job but that might not be what buyers are looking for. Has anyone sold similar engines weathered versus box new condition?”
