Thanks, Kat! I've been thinking about how I could have handled my dust test better. I wonder if the back would have been the best place. (Horizontal stripes might still be unfair to the product closest to the bottom.) Oh, and I need to add to my notes that I did let the VX sit for 2 days after applying the treatments. Should also mention I use a mild car wash soap (Meguiars).
Your comments about rubber reminded me why I expected the Meguiar's to work better. I've used that on tires for years and it will still look very good after 2 - 4 washes. I think you're exactly right about it absorbing better into softer surfaces.
I'm wondering if it's actually possible to get the cladding completely dry after applying 303. I'd used a clean terry towel to dry it, but like I mentioned in my write-up, "tape wouldn't stick to it." (I made another attempt with headlight restorer yesterday and taped around the lights to protect the surrounding surfaces.) Maybe it just wasn't absorbing because I'd used that towel before for removing wax or something and the previous chemicals didn't wash out completely.![]()
