Hello, I'm not a professional detailer, but just looking for a good product to protect my cars for the winter -- 2009 silver infiniti and 2006 silver ford fusion. I've done a little reading online and while Klasse looks like it would do the job, the high gloss sealant may be more work than I'm looking for as several posters have said it is tricky to remove. What prodcut would you suggest that balances good protection with ease of application for a novice? I'm hoping for about 6-months of protection to get us through the Pittsburgh winter. Thanks very much.
