Protocol

How we run it in the bay.

For faded trim. Not for paint. Trim Lock is a silicon carbide (SiC) infused trim coating for exterior plastic, rubber and vinyl. It soaks in; it is not a quick wipe dressing. Silicone-free and dry to the touch.

  • Trim coating, not a dressing. Apply it, let it soak in, then knock down remaining high spots.
  • Revives faded trim. Grey, chalky plastic looks dark and clean again.
  • Silicone-free. No sling, no greasy shine.

Why we run it in our studio

Grey, chalky trim rolls into our studio every week. Trim Lock is what we use to bring it back to dark without the greasy dressing look that attracts dust.

The Shop Protocol

  1. Clean. Clean the exterior plastic trim thoroughly. It has to be completely dry.
  2. Apply and dwell. Put a small amount on the Foam Applicator and apply it evenly. Let it soak in for about 5 minutes.
  3. Knock down. Wipe off any remaining excess (high spots) with The Swiss 16×16 10-Pack. Keep product off painted panels.

Pairs well with

Trim Lock is our dedicated trim product. Wash the trim with AQUA-SUDS and let it dry fully first. For paint, use Katch 22 or VITRIFY MAX.

How long the trim layer holds depends on your wash routine, weather and prep. Watch how water behaves on the surface and reapply when the beading drops off.

    Works on rubber seals too

    Posted by Russell N. on 16th Jan 2026

    Applied it to the rubber window seals and door seals on my truck. They look new again and the rubber feels protected. Keeps them from drying out and cracking. Unexpected bonus use for this product.

    Easy application

    Posted by Maria G. on 30th Dec 2025

    Was expecting this to be complicated but it's straightforward. Apply with an applicator pad, let it cure, done. No buffing, no multiple coats needed. One coat gave me perfect results. The trim on my Highlander looks better than new.

    Used it on my motorcycle too

    Posted by Phil H. on 29th Nov 2025

    Applied Trim Lock to all the black plastic on my motorcycle — fenders, engine covers, side panels. Everything looks deep black and the finish has held up through rain and highway riding. Great product for bikes.

    Great results!

    We have a new 25 Outback Wilderness. The trim on this vehicle is not the usual soft plastic. It came home from the dealer with streaks etc... on the trim. I was wary to put anything on the trim out of fear of making things worse. I didn't want to use a regular ceramic that would just seal in the streaks. After speaking to and trusting Landon, I put Trim Lock on all the trim. Whether it removed or covered, all the streaks, spots are gone and the trim looks perfect! One coat, around 25ml of product.

    My faded trim looks brand new

    Posted by Brian T. on 11th Sep 2025

    The black plastic trim on my 2019 4Runner was turning gray and chalky. One application of Trim Lock and it's jet black again. That was 3 months ago and it still looks perfect. No reapplication needed. This stuff is legit.

    My whole family uses it

    Posted by Vanessa C. on 10th Sep 2025

    Started using this myself and now my dad and brother both order it. We all live in condos with no hose hookups. This product lets all of us keep our cars clean without any hassle. Highly recommend for anyone without traditional wash access.

    Better than any trim restorer I've tried

    Posted by Angela M. on 24th Aug 2025

    I've used Back to Black, Cerakote trim coat, Solution Finish — all of them. Trim Lock outlasts every single one. It's not a dressing that washes off; it actually bonds to the plastic. My Jeep's fender flares look factory fresh.
