[AlumaClear] TCI-503 HD is the BEST! It took a dull trailer that hasn't been washed in 6 months back to SHINE!
I use the [AlumaClear] TCI-503 to clean my trailers and it is a great product! It works just as described! It doesn't turn your trailer white, instead it brings back the original shine. It easily takes the winter brown off of my trailers! I have tried a lot of different products and this is by far the best!
