Correct, I should have written best left to the exterior, sorry for the confusion. Opti-Coat Hyper Seal can be used as a drying aid, or as a stand alone sealant like Opti-Seal on all exterior surfaces.
Just got the Opti-coat pro Plus done a few weeks ago. Todd the detailer did a Fantastic Job. I cant state how happy and impressed i am at this product. I dont think the picture i uploaded does the result justice as it was a bit cloudy that day so i linked aideo walk around too Todd did for his business Facebook page.
