Mr. BILL,
Hello. LOL~.. hehe.. Thank you for the infomative info. Actually, I really enjoyed reading your reply. Very educational for a newbie like me=). Thanks again for the time you took to help me understand the whole process. I have noticed that MB tex seats(light beige color, for example) tend to get little darker in some spots after like 4yrs. Will lexol's vinylex get rid of those dark spots? I think MB factory Vinyl cleaner(by Meguiar) doesn't get rid of the dark residue that have accumulated on MB tex seats. Thank you again for your comments and suggestions. Take care.
