A lot of Aftermarket online retailers even sell on Amazon, you can’t help but plug it, cause they have about anything you need in one location… Just saying…
Online store just as one example, I’m sure I could post many more… lol
For the age of this car getting a new paint job the waxing question, IMHO, is much ado about nothing. Wait the recommended amount of time and then…well…do nothing. Or throw some wax on it - nufinish or maguiars or whatever. Makes no real diff.
The only thing I use paste wax on is my table saw top. I used blue coral years ago on my pontiac and couldn’t hardly get the stuff off again. I used turtlw wax on our 58 Chevy but pretty sure that was liquid. Hard to remember that far back but what ever you all feel comfortable with.
