Gtechniq C4 - Permanent Trim Restorer
I recently applied this to the faded plastic door sill (kick plate) on the 997. I like what I am seeing... The cure time is 12 hours before it can get wet. The box states that durability is up to two years for all exterior trim. “Restores trim to ‘as new condition’” Pic 1 is after it was applied. Pic 2 is after 19 hours of curing.
I have new ‘Carrera’ stainless steel doors sills, but the removal of the factory units are a pain in ass as the double sided taped used to hold them in place makes for a challenge to remove and then residue clean up is also tiresome. Far more than I am willing to deal with, especially given that my left shoulder and upper arm are still in significant pain from my horrific fall at the end of January.

Sorry, I do not… The driver’s side was more oxidized and was also splotchy in one area, almost like a harsh chemical was used on it at some point.
FYI, this product is clear so no dyes are used. Generally I am not overly impressed with Gtechniq coatings as I had the E39 professionally paint corrected with Gtechniq Ultra ceramic coating applied afterwards. Total snake oil with a BS nine year warranty. Edit: This product maybe the exception. Time will tell… Last edited by SCA; 04-16-2022 at 12:07 PM. |

That looks great. I've had good temporary success with Mother's Back to Black, but this seems better for sure.

I’ve had great results with Solutions Finish. Will be curious to see how these hold up.

Product pics.
I used CarPro Inside diluted 1:1 to thoroughly clean prior to application. Which even though it appeared clean it was not, plenty of old containments were removed. Afterwards I removed any remaining ‘Inside’ residue with a damp microfiber. BTW, ‘Inside’ at full strength will clean nearly anything, but caution must be used as it can be too much in some cases. Edit: I am debating adding a second coat to the outer door sills. What could it hurt? Nowhere within the instructions does it frown upon doing such. Last edited by SCA; 04-16-2022 at 05:13 PM. |

Am I weird? I just use straight peanut oil.

Plastic dye works a lot better than oil.
Also, Solutions Finish is about the same effort or less to apply as peanut oil.
