Re: M20 or M21????

That's correct, it's 100% synthetic.

You can apply UW as a very thin coat. It also uses advanced cross-linking which makes it last longer than M21 or Next Tech Wax 2.0 .

I understand your point that you'd rather experiment with it on your own time. Good way to get fully familiar with the product and see what it can do.

Re: M20 or M21????

Thank you that clears up a lot.

You know, I was thinking about UW but I just dont know I want to use it on this RV. It's for a customer and I need to KNOW it will last. He doesn't really care about the shine. I think the UW is too new to me to try it on this-maybe my vehicle first. I have a tin of it i plan to use soon and am looking forward to it.

How long are they saying it lasts? It is a polymer wax also, correct?

Re: M20 or M21????

Murr answered the first question I'll try the second one.

M21 goes on top of any cleaner wax without any bonding issues.
However M20 outshines it (finishes with more gloss) similar (not quite) to M26 High Tech Yellow Wax. But definitely M21 offers much longer protection.

Troy, how about Meg's newest wax - Ultimate Wax. It offers the best of both worlds - longest protection and great shine.
Our Administrator, Mike Stoops, posted couple days ago that he applied Ultimate Wax Paste with 4" Finishing Pad and DA polisher and even he got impressed (and you can imagine that not too many things in detailing world can impress him).

Re: M20 or M21????

That's what I was thinking too.

I am thinking M45 followed by Collinite 925 or M21 which would be better? How long does M21 typically last?

Re: M20 or M21????

M45 would be better for cleaning and polishing.

Re: M20 or M21????

Thanks guys.

Would M20 be better to use than M45 RV cleaner polish?

The RV is in pretty good condition with light staining.

Since I can top a wax M20 with a sealant M21? There won't be a bonding issue?

Thank you for replying and your help.

Re: M20 or M21????

Hi Troy,

There's some difference between these two products:

M20 Polymer Sealant is a cleaner wax and M21 Synthetic Sealant is a finishing wax (sealant).

I would say that if you finish not 100% LSP ready go with M20 but if you're satisfied with previous steps just protect your vehicle with M21.

Due to some mild cleaners and polishing oils in M20 you shouldn't really use multiple layers of that product. But you could top M20 with M21 if you wanted.

Re: M20 or M21????

M21 is newer technology and offers better durability and longevity.
That is not to say that M20 is not a great product also.

I have an RV coming up and would like to get everyones opinions as to which I should choose to seal it with.

I am looking for the longest durability.

Which should I choose?

Thanks!
