Unlike the Automotive Trim dressings you ve used before that easily wash off Trim Coat is a ceramic coating that restores unpainted plastic trim to its original glory and then LASTS for 200 washes or more - looking darn near as good on the 200th wash as it did on the first. Trim Coat trim restorer is a durable ceramic coating which bonds to the pores of unpainted plastic trim - restoring trim to its original appearance. But it doesn t stop there once applied it cures to form a ceramic layer of protection. We re so confident in our Ceramic Trim Coat technology that we guarantee it to last for at least 200 washes.
