If they are overly optimistic with the durability claims for the sealant, their coating's durability might be a optimistic as well.
The sealant claims 12 months of protection, but the detailers in the UK and Ireland were only seeing around six months. That climate is much milder than what is found in Scandinavia.
I simply asked the question to see if anyone here had been using the coatings long enough to validate the vendor's claim.
My issue with any durability claims or observations on any product is it's totally subjective based upon the individual and their vehicle and how it's cared for.
If one was to put an LSP on their vehicle regardless of products manufacturer is it garage kept, non garage kept, what color is it, is it washed weekly, is a maintainer used after washes etc etc etc.
So my point to durability estimates is that it's totally dependent on how the vehicle is cared for by each individual owner. My own assessment of durability would be to apply the lsp, non garage kept in the Florida summer season which is about 6 months long, maybe wash it a few times in that time period and apply no detailing sprays or liquid sealants and then see how it's held up.
Why you may ask?
Because that's real world car care for the average person who owns a car. They probably don't wax it once a year, occasionally run it though car washes etc.
We Geekers are the one per-centers.
I can share this with the forum, I put VC on my Rogue back in the end of December 2015 and I betcha I haven't washed it maybe three-four times since then and definitely not in the last two months. This time of the year it rains pretty much tropical downpour every day(it's raining right now) and the sun it relentless.
To me that's a real world test of Viking Coat.
I put Master Sealant on my wife's Sonata hood back at the same time and let it go about the same route. It stacks up against any of the sealants we talk about here on a regular basis.
What I will say is out of the other sealants I've done this with Powerlock in my tests performed the worst in my environment. I know there are a lot of PL fans, I just happen to not be one them based upon my personal evaluation.
WG 3.0 and BF WD did very well. None of them really lasted more than six months. Powerlock faded out in 2 months.
But on the other hand, take my garage queen. It has Invincible and Cosmic Coat on it and is driven only on sunny days and sparingly at that. Being it's garage kept what's the longevity of the coating?
Potentially forever?
It's not exposed to the elements for any period of time. It's only been rained on a couple times in 4 years and not in the past couple years.

rops:
So that being said, imho longevity claims are pretty much totally subjective and dependent on way too many factors. Just my personal observation.
That being said I have been very happy with the Viking Coat. I probably wouldn't wait a year or two to reapply any LSP anyway so the investment was worth it for me.
But I'm a product addict any way :buffing:
