Hi Valli
It’s not clear to me from how he was talking, if he meant treating the parts disassembled or assembled. As I read in other posts, treating parts disassembled would mean the glue would not work.
He said to dip one half in, then turn it around and dip for the other half.
The electric fry pan my brother has is 33cm x 33cm x 6cm. There is also a solid stainless steal roasting tray 30 x 37 x 6. The dimensions for the Flow Hive Langstroth 8 Deep are: standard size box width – 35cm, box height – 24.5cm, box length – 50.5cm, base length – 57.5cm. So looks like I’ll try the roasting tray over a gas flame.
best wishes
