Decon: Clay

Claying the vehicle’s painted surfaces is traditionally used to remove embedded and bonded contamination. Traditional clay and Synthetic clay are two types of clay used. To test if the surface needs claying use a “baddy test”. A “baggy test” is done by taking a ziplock type plastic bag and placing your hand inside it, then on a clean dry surface glide the bag on the surface and feeling the contamination on your fingertips through the bag. If you feel the contamination on the surface it needs claying.

The reasons to remove contamination using clay :

  1. Increase smoothness and shine of your paint.
  2. Increase the life of wax, sealant or ceramic coating as contamination interferes with their bonding.
  3. To prevent damage to your paint as the contamination, if not removed, will erode the paint.

Claying does not remove paint defects such as swirls/light scratches, deep scratches, etching from bug guts and bird droppings and clear coat failure.

SONAX Spray & Seal application

I have been testing SONAX  Spray & Seal for some time and here are some my observations:

  1. It lasts up to 3 months (in my care).
  2. It beads more than it sheets compared to other spray and seal products.
  3. It was also attracting dust similar to a wax but not as bad.
  4. I was able to strip it completely with a full strength APC.
  5. It definitely adds gloss to the surface.
  6. It smells like toothache liquid…lol.

Here is a quick demo:


  • Wash the vehicle thoroughly.
  • After final rinse leave the vehicle wet.
  • Apply Spray & Seal panel at a time and rinse the panel and the surrounding areas.
  • After applying it on the entire vehicle blow dry or use a drying towel.


  • Don’t apply in direct sunlight.
  • Be cautious of applying in windy conditions as you may be chasing overspray.
  • Don’t apply directly on windshields.
