What's Inside a Winnebago Wall?? RV Sidewall Water Damage part 2

This is the inside of a Winnebago sidewall. There is framing in there. Chad and I continue the teardown, treatment, troubleshooting, and re-lamination on this 2006 Winnebago Journey.
This is not a bus monocoque construction but a laminated sidewall.
We are using STABOND 440 and 183 for this repair.
Thanks for watching!!!

And yet again a good example of why i think slide outs are a horrible idea. I've got got a 20' camp trailer that I've got to skin and rebuild and you've got the best educational vids yet!

[@brendacalderon9445]

We bought a rv with delamination, the seller tried changing the subject and we really didn't know as we're first time buyers, ughhh! And he said he told my husband it had a leak in shower skylight but he repaired it, but when I asked about the bubbles he said he didn't know and it's below floor level but it's not it's on back shower wall and also below floor level. The bay metal roofs are damaged to where foam is falling along with holes in the metal and ants. So we just waisted money.

Good to see a fellow Samsung Note 9 user! I was nearly ready to put my 2005 Winnebago up for sale after watching your roof and j-channel videos. This may clinch it! I'd like to know if that coach lived in a super wet climate. Seems like quite a bit of rust on what little I could see of the chassis. I don't have any of that, so maybe this has been exposed to a lot of rain. Thank you so much for documenting this, it really does show that owners need to keep up on maintenance, especially the areas way above eye level.

[@ckm-mkc]

That is a huge amount of work and you guys are doing it right. I'm just shocked at the shoddy construction, it's not like no one knows how to build watertight walls e.g. boat builders do it all the time...... Esp. given the cost of these things, the profit margins must be massive - that said, it sounds like they are using 1970s construction techniques - boat builders moved to vacuum bagging decades ago as it is way more efficient.

[@AZExpert]

A few manufacturers do use vacuum bagging and I think it is becoming more common, but unlike boats and planes these things don't sink or fall out of the sky so the bar is pretty low. :)

[@augiemattheiss]

I hope you make good money, it is very obvious you do the best you can on really messy rework/repair jobs. I'd look at something like that and run in the opposite direction! I do really like adhesives , under proper conditions, used correctly they are crazy strong. Some car companies glue their car body panels on, wild! ....

[@AZExpert]

I think I prices are much lower than would be expected at most shops. I am amazed how strong adhesives can be. Prevost glue there stainless body panels on too.

[@PhilipZurcher]

This video series, Part 1 and 2...(3?) has been so helpful. My CC has this exact issue but I believe the water damage came from around the windows. Both damaged areas have a window that the wood framing around the window is rotted. Plus CC does not cover the entire outside layer with foam so the framing is exposed unlike W. The CC exposed steel framing is now rusted due to the moisture and would have to be cleaned and treated before repairing. Is there a product that can be used in lieu of Lauan that would act as the barrier between fiberglass and foam? That way the week point (Lauan) if it got wet it wouldn't separate and cause de-lamination? On my coach and this one and all others that had the de-lamination issues visible from the outside the only issue is that the three layers of wood sheets that Lauan is made, separates from and then there is no structure bonding the wall. Love your channel and work ethic, expect an email shortly:)

Thanks for all the helpful videos. I do have one question. Why don't you and Chad have a long handle floor and ice scrapper to slide under the fiberglass to break it away from the luan?

[@AZExpert]

not too many places in Phoenix stock long handle ice scrapers, I thought I had one, but the handle was too long anyway and the shovel worked well.

[@lutomson3496]

Great video i would have continued on with the rear and find the leak, isnt there a thermal imaging camera you can use to scan these roofs and walls to determine how much rot there is behind? You can rent them... Keep the rig cool in side if hot outside or hot inside if cool outside, rotten wood doesnt conduct heat and with a thermal imaging camera easy to see leaks damage without tearing apart, they use this on houses and i think it might work with you guys, anyway great work!!

[@AZExpert]

I appreciate that, the wall did feel very good above the loose area and neither the owner or I wanted the cost to get out of hand. Thanks!

[@rockeyoliver7254]

James, thank you for this part 2. Please educate me about the foam. After using fungicide, could a person spray a coat of kilz on the foam? I thought about this when watching the video, and thought I’d ask your thoughts about this? I’m definitely looking forward to seeing your next video regarding this repair. Thank you.

[@AZExpert]

I would not recommend it Kilz would just coat the foam and keep the wood from sticking and of course mold won't grow on the foam only the wood.

The roof inspection videos are much easier to make.

[@johnswan9123]

The corner reminds me of chimney flashing corners where an overlap (uphill side) is needed and therefore double flashed. I think haste at the factory causes a lot of this.

Seems likely

[@rickl6697]

James, I'm fixing a bay door on our 2003 Newmar and it going to involve glueing filon to styrofoam (white), (I think the outside painted surface is filon, Newmar said it might be plastic,??

A new 46" bay door is almost $ 800.00 plus I'll have to paint it or have it painted. The paint on ours is nearly perfect so I'm going to attempt to fix it.(delamination between the filon and styrofoam. Thanks

[@thom7yv01]

What is the name of the adhesive remover that you sprayed on to get the glue off?

[@Cbarrier89]

What sta-bond do you recommend for this work? Can you also recommend a spray gun for the sta-bond as well?

[@AZExpert]

440 and 183 are the glues we use and a simple harbor freight spray gun.

[@cheneybros]

So, is it even worth putting on like a kilz paint on the thin wood panels you are gluing back on there? It seems like if you put on some kind of treated wood it would repel water better than just untreated, imo. great series! I say I am going to tackle my class C but after watching you do this, it looks more & more like a professional job, OR just scrap the damn thing OR tear down the whole thing to the chassis and rebuild something totally new. LOL!

[@GBuds_RVremodel]

In aviatio, industry there are elastomeric fillers and those would have worked to relevel the sidewall and the RV wall itself.

Thanks James. What amount of work goes into cleaning the paint gun after spraying the adhesive.... what solvent and precautions on minimizing overspray and cleanup ? JwgK

[@AZExpert]

thats the beauty of a cheap glue gun, most of the time if glue is kept in the hopper, the gun does not need to be cleaned, and if it does jam, replacement is cheaper than cleaning especially with the 2 year warranty from harbor freight
