I agree - pass.
I don't know what they think they would be adding to make it worth your while. I always ask myself, if the treatment was significantly
better than the non-treatment, than why isn't the manufacturer doing it at the factory? I know that doesn't always apply (e.g., Eternabond should be used by FR factories) but the logic usually holds up pretty well.
Also, sometimes its not even recommended. My roof is an Alpha TPO and their literature says there is no need for roof treatments.
It does not require the periodic application of products to protect it from ultra-violet light or ozone. In fact, these products can often cause damage to the roof membrane.
Maybe Primetime roofs need a third-party treatment but I don't believe it.
As for the interior, I wonder if they are scotch-guarding. What else could they do?
Paint treatment - is that waxing?
I really question these things.
