This will be a two step process just as if you were using two different types of polish so yes you would wipe off the polish as you work.
ULTIMA PAINT PREP PLUS APPLICATION INSTRUCTIONS
Use Sparingly: Ultima Paint Prep Plus can be used sparingly. About two to three ounces of product is all that's needed to polish most cars.
Preparation: You will achieve the best results with Ultima Paint Prep Plus if your vehicle is clean and completely dry. Thoroughly wash and dry all surfaces. If bonded contamination is present, deep clean your vehicle's paint with the Ultima Elastrofoam System. Park you car in a shaded area and allow to cool before application.
Hand Application: Dispense 3-4 dabs of polish on orange side of an Ultima Dual-Foam Exterior Applicator and rub it into you paint. If removing swirl marks or visible oxidation, rub briskly. If you paint is in good condition, there's no need to rub heavily. Apply to one panel at a time. As needed, apply more polish to the applicator. Rub until only a fine film remains. Buff off with a microfiber buffing towel to a brilliant shine.
Machine Application: Dispense a ring of polish in the center of a 5" to 6" foam "swirl remover" pad. Adjust polished speed to the mid-range setting and place the pad on your vehicle's surface. Apply firm pressure then switch on the polisher. After distributing polish on the panel, let up on the pressure and work in well. Run the machine until only a fine film remains. Buff off with a microfiber buffing towel to a brilliant shine.
Frequency of Use: Ultima Paint Prep Plus is a very gentle polish. Use twice a year as a pre-treatment prior to applying Ultima Paint Guard Plus.
More Shine: If your goal is the wettest-looking, deepest, clearest, most distortion-free finish you can imagine, after removing swirl marks and oxidation, Ultima Paint Prep Plus can be applied by machine with a soft foam "finishing pad" to achieve show car quality results.
