3M Perfect-It III 05933 & 05937--Worth Keeping?

I bought a quart of 3m Perfect-It III Rubbing Compound (05933) and Machine Glaze (05937)...er...20 years ago, when they were being discontinued, because a lot of people here on the forum really liked them. I don't think I ever used either of them.

In the interest of clearing up some shelf space, does anyone think these pre-SMAT polishes are worth keeping?

Look what I came across a week ago. It has to be at least half full. I’d also like to know if it’s still useable. Hard to believe it’s been at least 15 to 20 years since I purchased it. Ah the good old days.

Setec & Vegas1- Predictably, I'd keep them if they haven't dried out. Especially the 05937. The only reason I'd waver on the 05933 is that there are newer compounds that are at least as good in any respects I can think of. The 05937 OTOH, I simply *LIKE*. No excessive oiliness, decent performance, nice finish.

Well, ok then. Maybe I can get myself to throw out my bottle of Menz PG.

Thanks for the info Accumulator. It’s definitely still in liquid form. I just can’t remember why I stopped using it. I think I’ll give it a try on my son’s vehicle come spring.

Well, speaking of "old" detailing products , I have some Presta Chroma 1500 Polish, PN 133532 and Presta Strata Ultra Cutting Creme Light, PN 133423. I think you used the Ultra Cutting Creme first then follow with the 1500 Polish. Bought these twin when they were all the "flavor of the month" (remember that term?) and used it a BMW and a Chevy truck. Worked OK , but it they are really designed for Presta wool pads and a rotary, NOT for the Porter-Cable Dual Action 7234 and 4" LC pads. I found out this is THE polish of choice at a body shop nearby who's reputation is high-end repairs and paint jobs. Well that was in 2007, if I recall correctly. I bought these twins from a local distributor of Presta products and paid through the nose for the two 32 ounce bottles
(like $48 for the two, which is outrageous even today by my frugal Captain Obvious economic standards). There they sit on the back shelf about 5/8 full.

And, do any of you Autopians write a date (LIke 01Mar25) on a detailing product when it was first opened and used? I do this on food items (spices and seasoning being the main one's), just to get an idea how old they are and how often and much I use them. I think the same would apply to car detailing products, especially for those of us Autopians who detail "occasionally". Just food for thought (pun intended!)....
