Unfortunately that works both ways. A couple of years ago, I picked up a part-built Backwoods Miniatures kit for the Industrial Garratt. Whoever had built it (to OO) had used Araldite throughout - body, both chassis, cylinders, the lot. It took at least a month to carve and scrape the dried Araldite off and separate all the parts for proper solder re-assembly; the stuff was everywhere and had set very hard. A proper nightmare. Dunno why people do it that way.
