I don't think #101 has any abrasives. Below I will paste a response to an email I sent asking questions about the products. It seems that basically, all of the sealants are the same base product with varying amounts of CHEMICAL cleaners. #501 has the most, followed by #105 and #111 with very little cleaners.Not sure where #101 falls here, my GUESS would be between #105 and #111. Interestingly, the MSDS sheets give the same description for all four products.
I think if you want mild abrasives, you need to go #652 Pre-Cleaner, which I have used and like.
"Mike,
Thank you for your inquiry. All of these will give you the glossy look and durability you are looking for. The difference in the products is the amount of cleaning agents in each one. Part #111 has the least cleaner in it. This is used for new vehicles or ones that are kept polished regularly and do not need extra cleaning. The 105 and 501 has the most cleaners in them. 501 has a little more than 105. Depending on the condition of the surface, such as oxidation buildup, environmental conditions, etc. Either one of these would take care of these issues. The 601 Bonding agent will work with any of these and will help prolong the durability and protection of the polishes."
