When I first got into detailing, I did watch some of Pan's videos and they were instructive and helpful in terms of techniques and "how to's". But after having seen videos from other youtube detailers, there is definitely a difference in Pan's product reviews that I do not care for. Specifically, because he never says anything negative about the products he showcases, you can't help but wonder if he is getting paid to advertise the products. I feel like I am watching a slick infomercial instead of an honest review. Plus, he has given some glowing positve reviews for products that many other reviewers panned (no pun intended).
Here are examples of other youtube detailers that, as a consumer, I found more informative and honest. As a result, I trust them more than Pan:
Brian from Apex Detail - He will give honest reviews. He has said outright "this is a horrible product" such as his review for Topcoat F11 and he also says honest, mildly critical statements like "not the highest jump in gloss I have seen on the channel, but decent".
Car Craft Auto Detailing - This detailer from Australia gives honest reviews. For example, here is an honest review of Beadmaker he did in which he identified some real problems with it (very poor durability and interfered with the hydrophobic properties of some ceramic coatings). BTW, Pan, in contrast, said nothing but glowing things about Beadmaker and even ranked it as one of his top 3 sealants of the year:
Jimbo - Although he may not be as slick and eloquent as Pan, he does give honest, critical reviews. In your post, you mentioned Pan testing 3 sealants and how they all hold up. Here is an example of a video by Jimbo in which he tests 5 sealants. He clearly has some critical things to say about some of the sealants tested. You would never hear such criticisms from Pan:
I believe Chicago Auto Pros also show F11 Topcoat and Beadmaker failing extremely quickly in this recent video:
Right around the 24 minute mark, they talk about how they basically think the F11 Topcoat is an awful product that potentially rises to the level of a scam.
