Gtechniq C4 Permanent Trim Restorer 15ml

C4 permanent trim restorer is a nano composite coating which restores trim to “as new” condition without altering the gloss level.  A strong UV absorption filter and chemical bond ensures maximum durability with a single application typically maintaining a flawless finish for up to two years. 

The Tech:

C4 utilises a chemical bond to actually become an extension of the plastic molecule it's protecting.  Not to be confused with much weaker electrostatic bonds used by other coatings, C4 actually swaps part of its molecular structure with the surface molecules of your car's trim.

What this means is that you now have a protective coating of unparalleled durability and since C4 is an exceptionally thin (circa 30nm) optically clear film it doesn't add an unattractive gloss film to the surface instead it restores all but the most faded trim to an as new condition. 

Directions: 

C4 is a relatively easy product to use but correct preparation and application is essential.  Full instructions can be found here.
