Re: 20 or 21

We have used #20 for years. We have recently introduced #21 into our arsenal.

Are rules for which to use is like this-

#20 for vehicles in excellent condition needing a preventative maintenance type of "wash and wax"

#21 for anything that we polished/buffed.

Re: 20 or 21

Does M20 have mild cleaners like NXT liquid?

NXT is not a cleaner/wax so M20 can't have cleaners like NXT Tech Wax. M20 is a light cleaner/wax, so yes it has does have cleaners and yes it is formulated to clean mildly neglected paint.

M20 Polymer Sealant is a really good polymer sealant, give it a try sometime.

Re: 20 or 21

If 20 is a light cleaner/wax and the e-store has this to say for 21 "Elminates fine scratches and swirls, creating a flawless finish..." does this go to say that 21 is a light polish or "filler"?
TIA.

Re: 20 or 21

I just found that M21 works well in the hot & humid, here in NC it gets kinda nasty in July and August and I had NO issues at all with application and removal. I used a PC to apply. MF towel to remove.

I have been using #21 here in Humid Florida for almost 2 years. I have not seen any issues with the humidity.

It has filling abilities- which, contrary to some wildly odd misconception is actually a good thing for a wax. Some people swear all fillers are bad, but IMO a GOOD wax should have fillers.

Re: 20 or 21

Yeah really...

I can never understand why anyone would even care about a wax having fillers. Afterall, you've removed the defects, so the filling properties won't matter!

Then there are those that claim all Meguiar's protectants fill like crazy, but haven't even tried them. What gives...

Wax doesnt have fillers... Wax is a filler....

I am a newbie... and didn't know that all defects in paint can be removed.

I own an 88 Civic. My car hood has a lot of subtle "checking" which jumps out in bright sun. Nevertheless, since using Megs, I get a lot of complements on how great my car looks.

Last week, I did a "squeak" test on the hood with a terry towel to see if it was time to re-wax.

The paint is so old that I am guessing the engine heat has pushed the paint away from the primer. Therefor, a couple of tiny micro-dots of paint popped off revealing a white base coat. This was caused by defects in the paint and maybe defects in the guy using the towel.

It's my newbie understanding that in selecting a product, one first has to have a purpose. At my skill level my purpose is not to correct the uncorrectable, but to make the uncorrectable look corrected.

After reading this thread, I am going to try M-21 and top it with NXT. Hopefully the NXT will just redissolve the M-21 and not pull the M-21 corrective ingredients out of the micro cracks in the paint.

Are there any protectants that don't leave stuff in the cracks. How do they do that?

Re: 20 or 21

Is #21 also good for sealing painted aluminium rims ?

How many layers do I have to apply so that brake dust and the other grime easily goes away ?

Thanks !

Re: 20 or 21

To answer your question, does the #21 make it bead or sheet? In my experience when the water hits it. The initial reaction is to bead. Then the sheeting properties take over.

Re: 20 or 21

beading and sheeting would be the same property--- Hydrophobic. The only difference would be if the water is sitting on a surface (beading) or sliding (sheeting).

Re: 20 or 21

can M21 be used by rotary

[Murr1525]

Re: 20 or 21

Yes, #21 can be used with a rotary.

Re: 20 or 21

REF: beading/sheating, wasn't there a product out some time ago that claimed to make all water from all panels to sheet? virtually drying the car? i'm not talking about the auto dry deal but an actual wax?

anyway i tried the "flooding" technique today and it was a great improvement from rinsing with a nozzle.
