My comment was just me thinking out loud after reading these next couple of posts..
Why? For testing purposes. Not only was it his 1st time trying the product, but his 1st time ever trying a coating.
I guess I can naturally relate with OP, becuase I happen to love testing and experimenting with just about every product on my shelf..
Which is why it was simple and obvious to me why he only coated his hood. I would've done the same exact thing.. As a matter of fact I did do the same exact thing the 1st time I used Mckee's Paint Coating, I didn't coat my entire car no way, I wanted to test and see the differences between panels.
