Waterproofing from the inside?

[malconium]

I have just about decided to remove the inner wall panels on my 1973 31' Sovereign to redo insulation and perhaps add to the wiring. If I do remove the wall panels I was wondering if it would be worth thinking about adding some sort of waterproofing to all the seams from the inside before I button things back up. I thought of maybe using some sort of elastameric roof coating - very flexible and stretchy.

Does anyone in the forums have any thoughts or direct experience with this?

Thanks,

I think you will find that a similar coating is on the inside seams. It was on the inside of the front dome I saw in Vermont. There they were removing it for allergy reasons. I would think some coating could only help. Prehaps this is another place silicon could be used. You want something flexible, good adhesion, and water proof. Able to tolerant the high temp of the sun in the summer and freezing in the winter. Also want something known to work and not experimental. Sounds like a job for roofing tar to me. I wonder how that smells at 150 degrees.

I was thinking of using a product called Snow Roof. There is a write up about it at the following site:

I would not expect it to have any oder like roofing tar would.

Did you try any of this products? and did it work?

Thinking of doingthe same thing.

I did not pursue this approach further. I did use Vulkem sealer in some places from the inside. I still think the idea is not a bad idea but I do not know for sure how well the available products will stick to aluminum. Another product to try is a DIY coating that can be used for truck bed liners or on boat decks. Check it out:

I would be interested in hearing more about whether something like this works for you.

Listen to the VAP! they talked about this. Coyln Hyde of GSM vehicles uses an automotive body panel sealer.

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.

I used this on all the inside seams. It is the best product that I could find at the time. Porsche uses it, so does Mercedes Benz,on new cars. It is also the recommended repair material for body shops that work on these vehicles.
The key is that it remains somehat flexible, and is formulated for aluminum.
The product is on the upper left side of the flyer in the attachment.
