    Re: Do you use a cleaner before going to your LSP?

    It does appear that a majority of folks over at AutoGeek and Autopia apply Prep-Sol or an IPA solution before applying their LSP. They believe that the durability and longevity of the LSP, especially if it is a synthetic sealant, requires as squeaky clean a surface as possible. See, e.g., this thread:

    Does it really matter?

    Nope..never have, never will. Unless I'm testing products, which I did with Ultimate Quik Wax.

    My answer would be no as well, do a small section with glass cleaner and check my work, but that's it. I've never had any problems with my LSP holding up because I put it on after a polish.

    Nope. I wipe down my test spot after it's complete to check my work but that's it. I am no chemist but I trust the chemists at Meguiar's when they say that it's a system and designed to work together. I like the look that polishing oils add to paint. And at the end of the day I am just trying to make the paint look good

    i agree ^ the oils and other stuff in the polish must be put in there for a reason by megs chemist so i say leave it on the paint.

    Re: Do you use a cleaner before going to your LSP?

    Of course, not everyone who uses Meguiar's polishes then finish their work with a Meguiars' wax. So the question becomes, Are there some waxes or sealants that need a squeaky clean surface in order to bond to it? I gather that some synthetic sealants, because of their cross-linking polymers, do not bond well, or as well, when applied to a surface where polishing oils are present. It would be nice to know which sealants require a squeaky clean surface.

    But do carnauba waxes have this problem? Given that thousands of people over many decades have been applying various kinds of carnauba waxes to cars that have been polished and glazed with Meguiar's products, I doubt that bonding is an issue. But I do not have any direct experience or data to support my opinion.

    The reason for the IPA wipe-down according to those individuals is NOT to clean the surface to maximize adhesion of LSPs, but it is intended to remove "bad" polishing oils (per their viewpoint) that "hide" the true condition of the paint ("fillers" as they often call them).

    It's usually used only in the test spots to make sure the process is giving "true" results and correction, but is not necessary for the entire vehicle in most cases.

    Actually, Mark, if you read through the thread I cited, I think you will discover that many of those who now do IPA or PrepSol wipedowns are also concerned that dirt and polishing oils will interfere with the effective bonding of the LSP. In fact, it has pretty much become a truism on some detailing forums that polishing oils disrupt the cross-linking bonding of synthetic polymer sealants. It is my impression that this belief is now being extended, though not without controversy and dispute, to all LSPs, at least in the sense that a squeaky clean surface is intimated to be an optimal bonding condition even for carnauba waxes.

    Cheers,

    Re: Do you use a cleaner before going to your LSP?

    I do it before I do my winter sealant on my truck. I use opti-seal since I have had great luck with its longevity during our nasty winters. Anything that can withstand living on the ocean, next to logan airport(jet fuel) and driving 200 miles north every weekend on heavily salted roads and still bead after the winter is a winner in my book.
    If its fast, loud, and runs on a flammable liquid...count me in.
