Good product
Size: TRIM COAT KIT
Good coverage. I've had it on for about 10 days, and it's holding up better than any spray product I've used. Not perfect, but none of those streak lines you get with other products. It's been rained on twice so far.

Great product and easy application
Size: TRIM COAT KIT, Size: TRIM COAT KIT
This stuff is awesome. It’s very easy to apply, just make sure the plastic application area is clean but don’t worry about taking too much time to clean the area as long as it’s clean and dry. Made my ‘19 Pilot look brand new.

glossy finish for faded black plastics
Size: TRIM COAT KIT
I have already used this product before and the results were very nice. If you don't mind a glossy finish, this product will bring those old black plastics back to life. You get several mess free applicators in the box. The product dries quickly and will last about a year or so, in my experience.

Easy to apply to clean dry surfaces
Size: TRIM COAT KIT
Seems to work very well. Made the plastic trim and MIC hardtop on my Bronco look like new. After the two hour cure time it drys hard to touch. Not sure how long it lasts yet.
