Back in the summer (4-5 months ago) I applied 2 coats of LiquidGlass on my new Mazda6. Now I'm going to start doing a more complete detailing routine. I ordered the evaluation Wolfgang kit and want to try this new product out first. Is there any special prep I need to do to the LG-coated paint before applying the Wolfgang Pre-Wax Polish? I'll be using Meg's #9 to get rid of some swirls, and hopefully by that time I will have a PC.
