This video popped up in my Youtube feed today, which I clicked on because its an Aussie channel and car. But to me, there is some quite cringe worthy stuff going on here.
Firstly, the wash. Apart from using a foam sponge, one guy was washing the car, the presenter then following behind with a clay bar. To me, without the rinse before claying, he is basically grinding all the dirt suspended in the soapy water into the paint, in turn making more work for himself with polishing.
Polishing. I'm hardly an expert on rotary polishing, but to me he was waaay over working the hood with a huge wool pad and a heavy compound. Then he goes back and hits again with the rotary, then again with a D/A. The paint on these cars is not ultra hard or ultra soft, so a three-step correction is not really needed. Waaay overcomplicated and I hope there is some clearcoat left.
Protection. Considering all the time, effort and complication that went into the polishing, he then throws a 6-month sealant at the thing. On a daily driver, you'll probably get 3 months. Shame to not have coated it at.
Anyway, probably overthinking it, but then again, probably not.
