Try Denatured Alcohol, a house painter friend of mine uses this to clean his brushes in. After that wash with warm water and soap. I would try a small spot first and go from there. Hope this helps.
Mike just did a review on this exact product and stated that you use this product "backwards" from what we are used to, but as you do the steps per the manufacturers instruction it will all make sense. This stuff works wonders.
De-badge vehicle as much as possible, then you don't have to worry about it. These newer cars all have stickers on the badge backing, not like they used to be with holes drilled through the panel and nuts holding them on from behind.
Check with truck dealer's, Peterbilt, Kenworth, etc. Maybe even Ram, Ford on the dually trucks with aluminum wheels. I believe they clear coat the aluminum buds after polishing, but before mounting the tires.
Sure makes maintaining them much easier.
Have not tried any coatings / sealants, what order would this trio be applied and what time between different toppings? Sorry if this is a dumb question, still learning.
Our church has an angel tree, we pick a few ornaments which has the ages, sizes, of some needy children. We go out and get gifts that the children wouldn't get. Hopefully making the Holiday Season a little bit better.
