While we're on the subject of Tropi-Care, I have been beating on Steve @ Tropi-Care to offer a sample kit to allow everyone to try his products without having to make a huge investment. He finally has agreed and has posted a sample kit on his website containing samples of his polish and car wash and a microfiber applicator for just $10.00 shipped.
Here is a direct link to the sample kit.
