This product is amazing!
I used this on my aging my golf cart that sits in the Florida sun. The Trim Serum-Plastic Restorer did an amazing job of bringing out a glossy finish on all of the black plastic parts which are particularly a problem in the sun. Rain or shine, month's later, they still look the same. I also used the restorer on the headlight lenses of my motorhome; they look like new. It is truly an amazing product.

Works extremely well!
***Update*** It’s been more than 6 months since I applied this to all of my exterior trim on my 2002 Duramax crew cab truck. My truck sits outside in the scorching Florida sun, 24/7/365. The trim…ALL of the trim still looks great, however I’m thinking of applying another coat of Trim Serum to maintain the look, even longer. I’ve tried other products over the years. None of them lasted more than a few weeks before needing to be reapplied. I’m well over 6 months, now and could likely get another 2-3 more before the black trim would begin showing blotchy spots. Spent the money and get this stuff…Thank me later!!! 😉 One coat of this easy to apply restorer and my 22 year old truck’s plastic looks brand new! It’s maintained that look for over a month, now. My bumper covers, fog light air dam and the rest of my plastic trim looks fantastic! Even the weather stripping looks new. Well worth the purchase price. By the way, I have enough product left to do everything at least 5 more times. Also, there’s no greasy residue left after buffing with a microfiber cloth. I highly recommend this product! 😄

This stuff is GREAT. Period. Just buy it.
I own a Honda Element. I love it. I plan to keep it until the wheels fall off, because it is a musician's dream car. Anyone who's ever been in an Element knows there's a LOT of plastic, and that living in a place like Texas (in my case) is rough on plastic. And Elements are now a minimum of 12 years old. Mine is 18 years old...and in great shape. But plastic is plastic, and both the exterior and some of the interior plastic has lost its original pristine finish. I've tried other stuff. Meh. But this stuff? It's like a miracle. First, it's thick. Not quite honey consistency, but that's the general range. And it goes FAR. When you first apply it, you'll notice it makes everything shiny, but that subsides over a few days and you're left with DRAMATICALLY replenished finish. I used it on ALL of the exterior plastic body panels, dash, door panels...you name it...and barely used any of the bottle. And once a few days have passed it is absolutely not oily or sticky in any way--unlike the typical products of its type. It's just as if the plastic has been made new again. Sorcery? Who knows? And it lasts!! How long? I ordered this in JULY and after four months everything STILL looks good. If you're looking, just buy it. Great value, amazing results.

It's a little greasy, protects well, and brings color back.
I bought this stuff a while back and all I can say is that it works pretty good. I don't apply it as often as I should because I don't always have the time. I use it on things like the plastic bed liner on my truck, it's a lot of work but worth it when you're done, just make sure you clean the surface well before you apply.

This stuff is amazing. Buy multiple bottles you will love it
This stuff is incredible. I used it on plastic trim that is 16 years old and have used dressings before but this stuff makes it look brand new again. I applied it as directed on a round microfiber pad I use to wax the car. Let it dry and buff it. I have washed the car 5 times since I applied it and it still looks like I just put it on. I love this stuff. This is my go to product for detailing from now on. The seal and squeal is awesome too. I with they had a bigger line of products because everything g I tried so far has been so so go… and larger sizes would be nice like quart size in a squeeze bottle. But the stuff in the bottle is bomb!

Easy to use
This is definitely the best product I’ve ever used on my Avalanche cladding. It goes on easy and holds up really well. I would recommend it.

Doesn't last long
Easy to apply, but lasts about 3 months and needs to be reapplied. But looks great for 2 months before fading

Great stuff. I used it on the trim on my 10 year old truck. I also did the folding truck bed cover, rider mower, & a Weber Grill cover.

Looks great with light application! Really poor bottle though. It pops open with pressure & all that expensive liquid goodness can leak out!

Well after many years trying many different products on rubber and trim and being shocked at how bad most are, I decided to try this Lithium Trim Serum. And what a wonderful surprise it turned out to be. So easy to use and so very economical, it can be used without having greasy muck flicked up the side of the car or the ugly greasy looking rubber and plastic finishes. Lithium Trim Serum provides a low sheen finish to all rubber and plastic finishes just as advertised - it makes surfaces look just like new as shown in the photos. I am an extremely fussy person and Lithium Trim Serum so far is the best product by far that I have ever used and the rain has not caused the washed out run marks so evident with other products I see no point in ever changing product again because this is so good. I also found the best applicator is a soft nail brush on rubber and textured plastic parts - the results are outstanding. I am so impressed with their trim serum that I intend trying their Lithium Hide Rehab for my interior leather. If it is as good as the Trim Serum, I am a customer for life. Outstanding product on every front. And check out the bottle in the photograph - that is how much I used to do every external trim and rubber part on my car. Keep up the good work Lithium - excellent product guys.

Product arrived ahead of time. The seller even wrote me some tips on how best to use it. Haven’t gotten round to using it yet so will cycle back to this later with comments *update. Wow. Used product and my faded and UV damaged bumper looks brand new again. Previously it had striations patterning the front in faded greys. They’re gone now and the bumper is looking immaculate. Very impressed with this product. Used sponge applicator to apply, left for about 15 minutes, and then buffed with a micro fibre cloth. Very impressed. Will probably apply a second coat. Used less of the bottle than I expected.
