McKee's 37 Coating Prep Polish

Polishes and preps paint for coatings, waxes and sealants - no IPA or paint strippers required!

McKee's 37 Coating Prep Polish is a non-abrasive chemical polish that deep cleans automotive paint, ridding it of below-surface contaminants that will prevent a coating, paint sealant or wax from properly bonding.  Formulated without any silicones, waxes, sealants, polymers or fillers, McKee's 37 Coating Prep Polish leaves nothing on the surface, making it the ideal polish to use before applying any product that requires a 100% oil and wax free surface.

McKee's 37 Coating Prep Polish is the only polish specially formulated for application of permanent and semi-permanent paint coatings.  By creating a polish that doesn’t have any oils, waxes, silicones, polymers or fillers, you can apply a paint coating immediately after polishing your paint with McKee's 37 Coating Prep Polish.  There is no need to chemically strip the paint using isopropyl alcohol or volatile wax and oil removers.

Paint coatings have quickly become one of the most popular forms of paint protection thanks to their ability to provide years of paint protection.  For a paint coating to properly bond to the surface, the paint must be rid of gloss-hindering below-surface contaminants and imbedded dirt.  While most polishes will successfully do this, they typically leave a wax, polymer, oil or some type of filler behind, all of which will prevent a coating from properly adhering to the surface.  McKee's 37 Coating Prep Polish removes unwanted contaminants without leaving anything on the surface that will prevent a paint coating from properly bonding.

McKee's 37 Coating Prep Polish is non-abrasive and safe for all paint systems.  Formulated with an advanced blend of chemical cleaners, McKee's 37 Coating Prep Polish will make light colors appear brighter and dark colors appear wetter.  McKee's 37 Coating Prep Polish will intensify the gloss of your paint by removing below-surface contaminants that hinder the shine.  What’s more, McKee's 37 Coating Prep Polish will remove other topical contaminants including water spots, road film and light surface staining. 

McKee's 37 Coating Prep Polish can be applied by hand or machine.  This versatile polish has been tested and proven to be compatible with all paint coatings.  Like other products that bear the McKee's 37 name, Coating Prep Polish is exceptionally easy to apply and remove. 

Put an end to mixing up alcohol and spraying volatile cleaners on your paint and prepare it for a coating using McKee's 37 Coating Prep Polish.

Left Scratches
This prep is suppose to be non abrasive but left little micro scratches in my paint. I had to buff them out. I contacted McKee's customer service. They were very rude.

Worked at removing layers of sealant
I applied this per directions on the bottle making an X on a while LC pad using a DAP . It applied effortlessly and after several passes was able to remove the tough glaze. However with super soft paint as another reviewer states, it was difficult to remove and left a bit of dust behind. Now I read that I could have used a damp mf towel and that may have done the trick but I have never had this problem with Pinnicle paintwork Cleanser.
ProsRemoves layers of sealant
ConsLeft me having to buff a lot to remove

Super clean!
I followed the instructions and used nickel size drop of product on a white polishing pad and found residue to wipe off effortlessly. Repeated process for van and car. Coated both vehicles with DP Paint Protect and am now ready for whatever our Chicago winter throws our way.
ProsEasy to use. Easy to remove when following directions.
ConsNone from my experience.
