I've got an older 2005 era PC 7424(non-xp) and need to know which backing plate and pads to use for a metallic silver Subaru Impreza (soft paint)?

I already have a 5.5" Lake county backing plate but need pads and would also like a 3" backing plate and pads.

Also, if you could recommend a good AIO to use to clean and protect the paint that would be great.. Thanks!
 
while i just recently just got them and haven't used them just yet, the new megs 5" DA foam discs would be a great choice (many have been waiting for years including myself to offer them in this size!). they are low profile and seem to be perfect fit for the DA. can't wait to use them!!
 
Thx.. got some in my cart now.. how about for 3"? I need a plate and pad...
 
I'd like to get the new Meguiar's backing plates in the 3" & 5", to use with my PC. I have Dynabrade backing plates currently.
 
The W67DA backing plate is the correct size for 5" MF discs and foam pads.

IMHO you'd be best served with that backing plate and the Meguiars DA 5" Microfiber Correction System, plus a bottle of D302 Polish. You may not need the D302 for a lighter color like silver.
 
I would stay away from the Meg's MF correction system on a 7424. I tried that approach when my only polisher was a 7424, and the machine wasn't up to the task of spinning the pads. I bought a GG6 after that and the Meg's MF system worked well for me. I use my 7424 with a 3.5 backplate and 4" pads now, and it's ok for that.
 
i posted in another thread when i meant to respond here. oops. oh well.

i dropped Lake Country pads in favor of Buff & Shine, particularly because they have 4" flat pads that aren't stupid tall and aren't CCS. and Griot's has low profile 3" pads for tight spots (orange for correction, black for finish polishing).

with a PC, esp. an older one, i think the 4" short flat pads are super handy because you can eek out more correction power than you can with 5.5" pads.

in B&S colors, orange, green and black would probably be your best bet, with you using the green and black on that car, depending on what you are doing.

i too back the suggestion of the 5" LC DA plate and you'd just need their 3.5" for the 4" pads.

i noticed LC makes a 2 7/8" (3") DA backing plate now. that's cool. i've been using a 2 7/8" rotary backing plate with adapter - it's black and shaped sorta like a bell, not the yellow thing they sell on here now. i like it because it adds reach which combined with the little pad makes for a pretty handy combo.

this reco is for all of my fans:

Optimum Poli-Seal
 
I have every color pad and size. However, I find the smaller work the best as in 4 inch. For some reason, I blew out the yellow pads and they lifted off the black fabric.

Go smaller and the 6.5 are way too big for a PC in my opinion.

Could not disagree more

The Megs DAMF pads are perfectly suited for the lower torque of the PC

If you have poor technique and do not keep the pad flat to the paint, it will bog down

Mark your backing plate, to make sure it is not stalling out

I suggest machine speed of 5-6 with a PC for all pad sizes. Be careful with 3-4" pads at these higher speeds...if you don't keep the machine planted to the paint; they will go flying

I agree that there is very little that can't be polished with a 4" pad, but I do have the Megs DAMF 3" cutting and they cut very well on the PC

Resist the temptation to use a rotary BP with DA pads. Eventually, you will burn up the pad, backing plate or both

i do not like to use a rotary backing plate with a DA screw with use on the DA. IME the backing plate becomes loose from the screw and i don't feel comfortable for fear of damaging the paint if it comes/flies off. the best thing to do but might be a little pricey is to get an exact-fit custom DA backing plate from (kevin) buff daddy. he can make just about anything...

i put red thread lock on a thread or two of my adapter. i never had any issues but just looking at it when i first got the parts, it seemed like a possibility so i eventually got paranoid enough to use thread lock. i have had the plate long enough that AG doesn't even sell it anymore and it hasn't yet come loose. i had to take it apart only once to actually use on my rotary for a particularly challenging headlamp project and didn't have much of an issue, but i did reapply the thread lock when it went back to DA duty.

regardless, it looks like LC makes more than enough sizes at this point where you can just get a DA plate for anything.

+1

It was my understanding that system was specifically designed to use with that style machine. I never have issues spinning Rupes Microfiber pads, or Lake Country thin foamed wool on the pc.

Kyle - do you prefer to use your 1st gen 7424 when using the 5" or 6" DAMF pads as opposed to a PCXP or Griot's? I forget which other polishers you brought to the last SoCal meetup.

Honest question. Not trying to start a debate on your above quote. My experience has been different.

Since I purchased the FLEX, I can't imagine compounding an entire car with a PC

That being said, we have both corrected plenty of deeper defects down at Meguiar's HQ using the Megs machine with DAMF, so we know it works, just a bit more slowly

If I had to compound with the PC, I would definitely go with the 5" Megs DAMF with D300 or M100

I love my PC with 3" & 4" pads, especially the 3" DAMF
