Black Wow gets my vote for long lasting results and great looks and smell.
this.
ive used Back2Black, way too messy and attracts too much dust. not to mention its an OTC product so it only lasts about a week or so before the moisturizers in it wear off.
aside from this, you can start off by really treating your trims to Forever Black, which is a trim dye/restorer, and doing upkeep with lite amounts of Black WOW or any other product.
How do you guys use the black wow? i followed instructions and I was really disappointed, mine streaked and lasted like 1 week.
meguirers hot shot tire shine....works awsome on plastic trim....spray it, let it sit then wipe it away so its not greasy.
(detailer secret lol)
worked great on my honeycomb black grill on my silverado, just dont use it on the side step bar pads like i did. they looked great, but i almost fell out of the truck.
