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.
