A polish/sealant question

[Ern]

I currently have wolfgangs sealant on my hhr and I have put 1 coat of p21s on it a couple of weeks ago and im going to polish it with some xmt360 as I have yet to try it on black. Should I use a paint cleanser to remove the p21s and Wolfgang sealant or should I be fine?

IMO you always want to start with a clean surface before you polish... I'd strip the old stuff off and start from scratch.

You will be fine, the polishing will remove your wax and sealant

some people like to strip it first as to not gum up the pads as quick

Polish will remove whatever is already on the paint.
