MGH-4 Hand Cleaner - Still Good After All These Years! (http://meguiarsonline.com/forums/showthread.php?t=29062)

Over the weekend I used a bottle of MGH-4 Hand Cleaner that is Post WWII and probably from between 1950 and 1960 to remove stains from antique lacquer paint on a 1938 Packard Model 1603

Lots of people will join our forum and ask the question,

What's the shelf life of Meguiar's products?

The official answer is 3-5 years as long as the product hasn't frozen. That said, if the product has never frozen it's possible you can shake it up and if it still has a uniform appearance and consistency it's probably perfectly fine to use. Such is the case for this old glass bottle of MGH-4

Here a few pics...

A protective plastic wrap was placed on the paint to protect it while the car was transported from the East Coast to Palm Springs, California. After the plastic wrap was removed it was discovered that the paint had been mottled or stained after moisture got underneath the plastic.

That's awesome!

I have yet to try the Trim Dressing (M38 I believe) although not as old, but no longer available.

Good show :bigups

PorscheGuy, how long has your bottle been open for?

This type of stuff amazes me..

That's great Mike! That's cool that you used it!

Actually took a good selection of both old and new technology because this automobile had both antique single stage lacquer paint and modern basecoat/clearcoat panels. The doors, roof, hood cowl, and rear light components were all single stage, the main body and fenders were basecoat/clearcoat.

All of the antique products appeared to be completely fine to use and the antique can of M16 Professional Paste Wax was not only in perfect condition but this can has never been used and never even broken-in.



A few after shots, it's hard to photograph such a large car while it's in the garage...







After all the work was finished we toasted the survivorship of this classic Packard using some antique Meguiar's Mirror Glaze Glasses.

Black and Gold.... at least Meguiars knew good colors to choose... :D

Certainly cool though, doesnt seem to be the same variety of logo stuff these days.

The Packard looks fantastic. Those glasses are unbelievable. It is truly amazing that those products were still good to use after all these years. Thanks for sharing, Mike.

The Packard came out fantastic Mike! :xyxthumbs That is a lot of car to do all by hand. Were you able to get the stains polished out on one pass?

With all of the products at your disposal, what made you think of the MGH-4 Hand Cleaner to use for this project?

Solid work, Mike. That car looks better than it did the day it rolled out from the factory I am sure.

If you need an extra pair of hands next time you have a special project, you know where to find me ;) Haha.
