he blue foam is designed for compounding and swirl removal. This closed cell pre-polymer foam restores oxidized and heavily swirled paint. Looks can be deceiving; the blue pad looks coarse but actually finishes with no marring. You'll achieve an almost wax-ready finish in one step. That's another way the Lake Country Hydro-Tech 6.5 Inch Foam Pads save you time. The blue cutting foam works well with Menzerna Power Finish PO 203 and Meguiars Ultra-Cut Compound. Both polishes have great cutting power and a clean, glossy finish. Use either polish/pad combo on neglected finishes and watch the paint come to life!
