Not long lasting
Style: Trim & Plastic Restorer, 12 fl. oz.
Works well but might need multiple coats to get to shinny. Not long lasting.

Time will tell
Style: Trim & Plastic Restorer, 12 fl. oz., Style: Trim & Plastic Restorer, 12 fl. oz.
I sprayed off the shutters before using. Then applied the product. It’s a thicker, white liquid. (Think lotion) it applied easily and dried quickly since it was being absorbed into the plastic shutters and aluminum windows; mine were very ‘thirsty’ from being in the direct afternoon sunlight. I like how I didn’t have to worry if one part rcvd more product than another. It blended easily.
I think it looks good, but so did using other products over the years. I was told by a neighbor that this was the best product to use on them and other plastics. Time will tell if it holds up.

Great Stuff
Size: 120 ML
Product is good, Easy to spread for the most part. The only complaint I would give it is that the applicators do not hole up after several applications, I would suggest using a microfiber cloth to apply.

Restored My Trim Instantly
Size: 120 ML
I used this plastic restorer on the faded trim around my SUV, and the difference was immediate. The dull gray plastic turned back to a rich black color within minutes. It spreads evenly and doesn’t leave greasy streaks behind. After a few weeks and several rainy days, the finish still looks great. My car honestly looks years newer now.
