Just a thought..I've been applying "Wipe New" once a year for 4 years now, and it's so much better than anything I've used previously.
It also takes the scratches in your cladding to the same finish as the top of the cladding....I bought the last bottle at Bed, Bath, and Beyond in Spring 2015 for $19.99....literally, just apply once a year, and forget about dealing with the cladding for that year.
