Koch Chemie PW Protector Wax VS Koch Chemie SO 03 Hydro Foam Sealant!

Product(s) reviewed / compared

• Koch Chemie PW Protector Wax (PW) – a protective wax sprayed onto a wet, freshly washed surface and towel-dried.
• Koch Chemie SO 03 Hydro Foam Sealant (SO3) – a foam sealant (polymer sealant) sprayed onto a wet, freshly washed surface, with a short dwell time, then rinsed and towel-dried.

How both products are used (common user experience)

• Applied to a clean, wet vehicle surface after a wash (using a foam cannon/foam gun/pump sprayer).
• Dwell briefly, then rinse off (water reportedly “activates” the product, turning it frothy).
• Dry with a towel.

Dilution noted as a difference

• SO3: 150:1
• PW: 200:1
• The speaker suggests dilution can be adjusted depending on the environment.

Key observed differences (performance / protection)

PW Protector Wax results

• Described as “not very impressive” in the speaker’s prior test.
• Only minimal difference in slickness during wiping compared to SO3.
• In a side-by-side comparison, the speaker reports a clear “line” indicating PW’s protection effectiveness is less distinct.

SO3 Hydro Foam Sealant results

• Described as the clear winner.
• Produces a more obvious, definitive line through the panel where protection was applied.
• The sealant won’t wash off anytime soon (despite being spray-on/rinse-off).
• Feels slightly slicker during towel drying.

Claimed benefits / compatibility

SO3 is said to help complement and maintain:

• Ceramic coatings
• Polymer sealants
• Other existing protection

Suggested maintenance schedule

• Apply every other wash or every third wash.

Overall pros and cons mentioned

SO3 Pros

• Better protection and more noticeable/lasting results than PW
• Holds up well (speaker: “not going to wash off anytime soon”)
• Helps maintain existing protection layers (ceramic/polymer)

SO3 Cons

• No direct downsides mentioned in the provided subtitles (beyond general use steps).

PW Pros

• Creates a protective effect (foams and wipes off)
• Slightly easier to judge slickness (though only minimal difference is claimed)

PW Cons

• Not very impressive vs SO3
• Protection effectiveness is less clearly defined in the side-by-side test
• Speaker implies it’s not worth choosing over SO3

Comparisons / recommendations outside the two products

• The speaker criticizes the need for choosing a “second one” (implied: PW doesn’t make sense over SO3 for them).
• If someone wants a wax instead of sealant, the speaker recommends Montana waxes (extracted from brown coal), claiming:
  • better protection
  • higher temperature and abrasion threshold
  • dripping wet look
  • more satisfying application (though not spray-and-rinse)

Unique points mentioned (consolidated list)

1. SO3 is a foam sealant; PW is a protective wax.
2. Both are applied to a wet vehicle after washing and dried with a towel.
3. Water reportedly activates the product, turning it frothy.
4. PW previously felt underwhelming to the speaker.
5. Slickness difference between PW and SO3 during wiping is minimal for the speaker, but SO3 feels a bit slicker.
6. Side-by-side test shows SO3 protection is much more evident (distinct line).
7. Speaker believes SO3 sealant won’t wash off quickly despite being spray-on/rinse-off.
8. SO3 is intended to maintain ceramic or polymer protection.
9. Suggested application frequency: every other wash / every third wash.
10. Speaker overall calls SO3 the clear winner.
11. If choosing a wax, the speaker recommends Montana wax for stronger protection and appearance.
12. Dilution ratios differ: SO3 150:1 vs PW 200:1.
