I would be interested in hearing more about whether something like this works for you.
The inside seams, were supposed to be covered with "vulkem," sealer, when that trailer was in production.
The next step in the manufacturing process, which is still the same today, is to give the trailer shell a complete shower which contains a chemical that will glow when exposed to ultra-violet light, which is placed on the inside of the trailer.
Any water leaks, will show up, big time.
If you take the plant tour, you may see that in operation.
You certainly will see the water bath booths.
