FAQ
Frequently Asked Questions
What is OVERcoat Surface PREP?
OVERcoat Surface PREP is a multi-purpose cleaner designed for degreasing after polishing and before applying coatings. It removes oils, waxes, and residue from previous products to ensure optimal bonding of new coatings.
Can I use it on glass, plastics, or interior surfaces?
Yes! It’s safe for use on paint, exterior plastics, glass, and even interior panels. It’s perfect for light cleaning and degreasing across multiple surfaces.
Will it remove old coatings completely?
It can remove loose, non-bonded coatings, waxes, and oils from the surface. However, hardened ceramic coatings require polishing or mechanical removal.
What’s the difference between Surface PREP and an APC?
Surface PREP is formulated specifically to prepare surfaces for coatings without leaving residue. While APCs clean well, they can leave behind surfactants that interfere with coating adhesion.
Do I need to rinse after using it?
No rinsing is needed. Just spray, wipe with a microfiber towel, and follow with a clean, dry towel. Make sure the surface is fully dry before applying a coating.
Does it have a strong smell?
Not at all. OVERcoat Surface PREP has a fresh, clean fragrance—nothing like the harsh solvent smell of traditional degreasers.
Can I use it under direct sunlight or on a hot surface?
It’s not recommended. Always apply in the shade and on cool surfaces for best results.
Should I shake the bottle before use?
Yes. We recommend shaking gently before each use to ensure consistent performance.
Do I need to wash the car before using this product?
Yes, we recommend using the product on clean surfaces—especially on paint or plastic—to avoid scratches or uneven results.
However, for light cleaning of exterior glass, it can be used even if the surface is slightly dirty.
