Do you prime your blue/red foam pad when using a sealant on a PC7424XP?

I have been reading quite a bit on the forums about tips and tricks for using the PC 7424XP. I really am starting to come into my own in terms of polishing, but when using a finishing sealant on a blue or red soft foam pad, do you prime that pad as well? I have read its never good to dry buff. If you prime the pad, how much is required?

Yes & enough to coat the pad then very sparingly thereafter.

Thank you for the reply. When you say very sparingly would you say a quarter size drop per panel, or a bit more even?

When it gets too dry you will know when and how much product to put on.

I don't normally prime a pad for lsp unless I'm using a paste wax and machine.

I prime when using a paste wax by machine as you can see with Nicole swiping the paste wax across the face of a blue waxing pad in this article,

What's nice about DA Polishers like the PC, Megs and Griot's units is they are light enough and compact in size enough that most people can easily hold them with one hand which makes machine applying the wax fast and easy.

But when using liquids I just place some on the face of the pad and then start spreading. Can't hurt to prime the pad and if anything it could help but after you buff a few sections the pad will have self-primed simply through use.


If it's important to be uber careful and you're working on a dark or black colored car and you're doing show car detailing then by all means prime-away...

Mike, thank you for that explanation! My car is dark colored with soft paint, so I think a light prime may be my safest bet. Mike, after a light prime, what amount of sealant is ideal to add to the foam pad for the panel worked?
