If the paint feels rough to the touch this indicates you have bonded contaminants on top of your paint. These are things like tree sap mist, industrial fall out, road tar, and paint overspray. Use M34 Final Inspection with C2000 Professional Detailing Cay to safely remove bonded contaminants and leave the paint as smooth as glass. Finally, evaluate the paint for below surface defects. If you have light to moderate swirls, scratches, oxidation, water spots, or etchings you would want to use a product like M205 Mirror Glaze Ultra Finishing Polish, or M105 Mirror Glaze Ultra Cut Compound for heavier defects. Once the paint is free of bonded contaminants and below surface defects you are ready for wax protection. If the finish is neglected, pre-cleaning is recommended.Shake product well. Apply on a cool surface and in the shade.Apply a small amount of product on a Meguiars Soft Foam Applicator, Foam Finishing Disc or Foam Finishing Pad and spread thin and evenly on the paint.Do not apply to vinyl, rubber or cloth surfaces.Be sure to use overlapping strokes to ensure adequate coverage. Allow Meguiars wax to dry thoroughly (approximately 10-15 minutes). Remove using a clean, dry premium microfiber towel like Meguiars Supreme Shine Microfiber Towels. Please be aware that low temperatures and/or high humidity can prolong the initial curing time of the wax.One way to tell if the auto wax is dry and ready to be wiped off is by performing a swipe test. Run an index finger across the wax and if the wax smears, its not ready to be wiped off. However, if it's a clear swipe, the wax is ready to be removed.
