Magically becomes an external plastic new look.

Review by ohad, rated

This stuff is amazing !! My 7 year old car had plastic trim that looked dull light grey, and I had attempted to get all of the residue from previous paint sealants removed (without success). I simply followed the instructions, and the trim is now a dark grey, and cannot see the old residue anymore.
Also, the water beading is something I've never seen on plastic trim, it just runs off.
Yes it's expensive, but after 2 months, the trim has not degraded, and the water beading is just the same. If it lasts even a year it is worth it, and if I get 2 years its cheap for what it does.

Gtechniq C4 Permanent Trim Restorer

Gtechniq C4 Permanent Trim Restorer uses a chemical bond to actually become an extension of the plastic molecule it's protecting. Gtechniq C4 is not to be confused with much weaker electrostatic bonds used by, amongst others, ptfe based polymers, Gtechniq C4 actually swaps part of its molecular structure with the surface molecules of your car's trim.

  • Restores all but the most faded trim to 'as new'
  • One application can last up to 2 years!
  • Use on correctly prepared surfaces for maximum benefit
  • Provides thin clear film - does not add sticky gloss

What this means is that you now have a protective coating of unparalleled durability. Unlike many trim products on the market Gtechniq C4 is an exceptionally thin (circa 30nm) optically clear film which means that it does not add an unattractive gloss film to the surface instead it restores all but the most faded trim to an as new condition. You can expect approximately 2 years from a single application.
