Megs #4

On the product label it says "use with rotary buffer only" is this because of the heat produced by the rotary fully breaking down the product? Would the product not be very effective with a DA? What is the difference on ss paint vs cc? I spend alot of time on the forum reading and trying to educate myself but I couldnt find much on megs #4.



Thanks, Dave
 
#4 has been around a very long time, much longer that catalyzed urethane clearcoats. The whole formula was balanced around the paints that were put on cars “way back when.�



Which is not to say that it can’t work on new paint, only that it’s not optimized for it. And since new clear coats are very unforgiving when it comes to swirls a non-optimal product is less likely to give good results.



The abrasives in #4are very large compared to Meg’s newer formulas. You can actually feel them. They have a large initial cut and break down to a finer and finer cut. The idea is to remove a lot of material quickly and then remove marring left by the first deep cuts. If they break down at the wrong rate for a given finish they won’t be able to remove the marring and will just leave swirls, hazing or scouring.



A DA works the product very differently than a rotary and can leave scouring with #4. A modern catalyzed clear may need a longer work time or smaller initial cut depth or whatever.



For whatever combination of technical reasons, they found that the formula of #4 wasn’t keeping up with the needs of today’s finishes and paint shops so they created new products to meet the demand. They keep the old formulas around as long as customers keep buying them. Presumably, there are shops out there that have their processes dialed in with the older stuff and are happy to continue doing what works for them.

Thanks for the info! It seems like the old autoparts I go to here only carry old stuff thats probably been on the shelf forever, however I did find some more up to date products today at a local paint supplyer. I bought a small bottle of system one x3 to try instead. I think it might be a bunch of hype but Ive spent $12.99 on dumber things lol.



So basicly the entire mirror glaze line is outdated. I used #4 via rotary at 1500 rpm on my 20 yr old black ss paint and It made a huge improvment but did leave a few holograms. Could have been me to though. I have alot more respect for the pro's now because it seem's like this is dam near a science to know what products to use , how to use them, and technique.

Not at all.



Sure the old stuff is still there. But they add new products to the Mirror Glaze line all the time. The newer stuff like #21 and the latest products like #105 are great.



Occasionally they reformulate old products. The new version of #2 is no longer rotary only. It can be used by orbital, DA and hand.

Yeah I have some of that #2 also lol. I have to stop buying so much stuff but I also am trying to find the best combo for my cars. So far my favorate purchases are the Klasse twins,DWG, and RaggTop. I do want to try some Menzerna ip or sip. So many cars with different types of paint.
