Megs DA microfiber system / PC 7336

Just ordered the whole Megs DA correction system for my obsidian '05 LS. I have an older PC 7336. Is the old girl up to the task of moderate defect removal? Or should I upgrade my polisher. My wallet says no. I plan on making a weekend out of it and will be borrowing a space to work with, therefore, I don't want to waste my time/opportunity, if the 7336 is going to be a dog.


Can it be done?


Thanks!
 
Yes it can.  The 7336, is not as strong as todays tools but it is up to spinning the MF pads just fine.  I've done it with an old G100 (PC7336) and the Meg's MF pads.  Important to clean the pads after every section.
 
Differing experience here- neither of my older PCs (tried them both in case one was in need of another rebuild) is up to doing significant correction in a timely manner on hard clear, even with MF/M105.


Can it be done?  Yeah, but it takes far too many hours for me even with 4" pads (the overall fastest setup I've found for that machine).  Whatever my Flex 3401 and Griot's polisher cost, they were worth it.  And a Rupes 21 would be worth it if I did correction every year or two.
 
05 Lexus LS black is really soft (very correctable) paint.  IIRC, it is SS.  Cleaning up swirls doesn't take much on this paint.  I'd still think his old PC should be adequate.  But, I'd definitely recommend a budget for a newer polisher and there are several to pick from, all much more powerful than the old 7336/7424.  IOW,  I'd not be put off by using the older tool if I had not the funds readily available for a new polisher.  That paint corrects really easily.
 
jfelbab- Eh, maybe I'm just Mr. Doom-and-Gloom when it comes to the older PCs, but mine weren't all that great on medium-soft single stage (my Jag).  That sure doesn't mean it won't be fine on the Lexus though, so OK, I'll defer to your positive take on it.


 


I'm sorta sorry to hear the LS series has soft paint.  Not that I'd plan to buy one or anything, but I *do* kinda like them...that three-box styling gives them just the look I like.


 


Lust4Lexus- Hope it goes well for you, please post back if you get a chance and tell us how things turn out.
 
I had a PC - 7424 that crapped out before a year passed, lucky for me since the local DeWalt store did the full repair under warranty. The result was that it ran stronger and with MUCH less vibration. Brandon (who was big into detailing back then) came over, tried it, and said damn, i need to get them to rebuild mine - that thing is amazing! So, point is, you may have a machine that was built right from the get go and doom & gloom Eyor may have a one that needs a little work. I got a PCXP when that POS 3" Griots turd was returned to AG and they gave me store credit. I swear the old 7424 has as much or more over the new model, and doesn't tend to fall over when you set it down on its back.


 


Tips to the OP - since you bought the Megs pads, swap out often, they get hot and nasty, sometimes F'ing up your backing plate too. And get some M101 to bump up the juice with the D300, you'll likely need it in some areas.
 
JuneBug- Just a FWIW, both of my PCs have been rebuilt, the one has been done twice.  No question when they need it, between the noise and the bogging!


 


I *do* find it a little odd that others have better results with their 7424/7636 (are those the right numbers?  I have one of each of the original ones...) than I do, but I can't imagine that my two units/three rebuilds (think on that, the need for three rebuilds...it's a *LOT* of PCing!) were all abnormally wimpy.
 
JuneBug- Eh, after rebuilding they always behaved like-new (problem is, that's not saying much).  One of the rebuilds was sent off, presumably to a major PC service center (the local guys were embarassed that their rebuild didn't last longer).  Maybe I just have, uhm....unrealistic expectations where the 7424/7636 are concerned.
 
The above link is to a post by Chris Dasher ( PorscheGuy997). When the mf system was still in it's testing stage Chris used it on my Firebird to remove factory orange peel . Using D300, 1500 and 3000 grit paper , Meguiars mf pads along with his PC7336. These old machines are old and slow but they will do the job. Now compared to the current offerings of machines they are dinosaurs but they aren't dead yet. LOL.

 My old 7336 (made in the USA) was purchased in 1995 and has been serviced every year or two by a friend who runs an ACE hardware store.  They are a certified PC repair center. It'd get new brushes, commentator cleaning, lube and occasional power cords.  The old PC still runs great and I've gone through two 7424XP's since, both made in China and they became unrepairable within a couple years.  MY 7336 has always had nearly as much power as the 7424XP units I had.  I used to do around 50 cars a year so it would get a good workout.  Conservatively, this 7336 has seen at least 500 full details and probably another couple hundred one-steps.  I wonder if your old 7336 was made in the US or China. IME, the China transition destroyed the product.  
 
jfelbab- Mine are the older US models, from the late '80s/early '90s, back before they they were generally considered "polishers".  I.e., all the product info referred to them as finish sanders.


 


I actually bought the second PC as a test, wondering "did I get a lemon?" after so many people were favorably impressed with them and when I encountered contours my Cyclos couldn't deal with. But they both behaved exactly the same out of the box (and that's the level of performance that the rebuilds return them to).  I had been using my Cyclos, and the PC's relative lack of power (with ~6" pads, this is before I switched to 3-4") simply astounded me.  I remember how Griot's Machine Polish #2 (original version) simply *would not correct* my Jag's ss lacquer via PC/6", but did the job really quick via Cyclo.
 
Thanks for the responses guys! I bought mine about 10 Years ago from lowes. It was never abused. Maybe done the equivalent of about a dozen cars. Mine says portercable- Tennessee. Nowhere does it say made in China. I guess I have a "better" 7336. I'm going to go for it. I've spent so much on products already! But a megs 110 would guarentee great defect removal. Ugh! Don't want to spend more money! My paint is going to look spectacular though. What if I found a cheap 7424xp for 100 bucks? Would it be worth it or would I be better off with a gg, or megs machine?


EDIT: just bit the bullet and bought the GG6 gen 3 machine. I figure ill use the big pads on that and use my 7336 for 3 inch pad duty. Best case scenario. It's like a photographer with different camera bodies I suppose. Either way- I'm more excited about my results now. I'm ready.
 
Great choice. You'll enjoy the versatility. That's exactly what I use my PC XP for. Keep in mind that you probably won't need to crank up the speed to full tilt with the GG machine or else make sure to keep your pads cool. 
 
Lust4Lexus- Between this thread and your decision to get that bumpercover redone you're really brightening my day!  Good decisions, both of 'em.
