While his techniques are good, I would be wary of Pan the Organizers product endorsements. He is a PAID endorser, which will greatly influence his objectivity.
I enjoy ScottH, on youtube as he does not use paid endorsements. All his products are donated by viewers or he pays for them through donations. He does a lot of long term tests of products going on for over 1 year for durability. His tests can still be faulted for not actually driving the car on the road (road splash in rain can be hard on rocker panels), but about as good as it gets. He has ongoing tests of trim products, ceramic coatings, ceramic sprays, graphen sprays, paint protection films, etc...
