Interior/Exterior Sealing

I would be quite skeptical of these claims. Controlling humidity is the key to preventing mold growth. I don't know if a sealer would be able to do that. It might help if it meant that water would not soak into walls, etc. but I would want to know what product is being used so I could check out the claims for it online first. The same with the exterior sealant. I don't know of any one product that would be good for 5 years. I can't find any products in my searching the web that will last for 5 years without some sort of maintenance. Polymer paint sealants are much improved, and nano-coatings for boats (gel coat, like our R-Pods) only claim to last for a season. There are a few that claim to last for 5 years, but even those do not claim to be maintenance free.

Find out what product the dealer intends to use on both exterior and interior and check it out on the web before you commit to this expenditure. You did not say how many payments this would be or what the total price for this would end up being. Don't look at the $10/payment. Look at the total price and then decide if the claims of the dealer are worth the expenditure. you may find that you can do it yourself for a whole lot less than the dealer wants to charge.

Yea, I'm pretty skeptical myself and will definitely do more research on this before I make my decision, which will most likely be no...

Made the big decision this weekend and looking forward to picking up our new Pod in a couple of weeks. Dealer offered the DuraTain Protective Coating(s) (exterior, undercoating, interior textile, awning and leather).  They warranty the exterior/interior coatings for 5 years, under coating for 10 years.  Been reading various RV sites and comments do vary.  Some support purchasing (not inexpensive) and many are wary.  Curious if any R-POd owners on the forum have had any experience first hand?  Remember well the undercoating push when purchasing a new auto.  Consumer Reports advises against such
