Which PC? 7336 or 7424? Adv/Disadv to either kits?

WS6Fury · 02-20-03, 08:00

Just as the topic says, what's the advantage and disadvantage to either kit?

I understand from reading posts here that they are an identical machine, just different polishing heads/pads etc. One is offered as a sander, the other a buffer with a big thick pad of some sort??

Which one should I purchase, and what should I purchase to go along with the buffer. I will be removing scratches, hairlines, and swirlmarks and just regular old waxing.

Help a newbie with a machine

If you can't find it here, it would really surprise me.

Yup read the whole thing real quick yesterday, almost too much information for myself. The thing is, its so much info, it makes it very hard to pick out what the benefits are to either machine????

I just need someone to give it to me straight. Also, what pieces I will need to go along with the buffer.

Whether or not this is the "thing to do", I don't know. I do know, it is what I did.

1. Purchased the 7336 from Lowe's, came with a sanding backing plate, (of no use to me), and a screw on polishing pad. Many people say the polishing pad is junk and comes apart. I don't happent to feel that way, and still use mine with Meguiar's #9 for swirl removal, with no problem.

2. Purchased a Meguiar's W-64 DA Velcro backing plate

3. Purchased the Meguiar's WDAV99B Set of 2 polishing pads and 1 finishing pad.

4. Purchased 1 additional Meguiar's W-9006 finishing pad.

For an example of what the costs might be for getting enough pads and equipment for a start.
PC 7336 = $109 (Lowe's) This gets you the PC and 1 screw on polishing pad
WDAV99 = $32.95 + $5.95 shipping (Meguiar's) This will get you a velcro backing plate, 2 polishing and 1 finishing pad. You need to call Meguiar's and specify this kit, WDAV99, it is not on their web-site. I didn't know that when I ordered my pads.
You will have spent somewhere around $155.

If you shop some of the internet detail equipment suppliers, you can find complete kits, including the PC, backing plate and pads for about the same money as doing it one item at a time.

Hmm, I had hoped the bold-faced type I wrote this in was clear enough. Maybe I should change the colour and make it bigger?

The current recommendation for buying a PC is to simply buy a 7336 series model or buy the PC 7424 Bonus Kit from Coastal Tool.

The machines themselves are all identical, but have different cweights. Then get a backing pad and some pads from either Meguiar's (like Charles did) or CMA.

I believe the 7336 is a rotary polisher, while the 7424 is a random orbit. Here's what I know so far:

The 7424 is ideal for both amatures and pros. You can achieve beautiful finishes with it. Slim to no chance that you'll ever burn through paint with it cause it doesn't build up very much heat.

The 7336 should be used by somebody that knows what they're doing. It can burn paint pretty fast (depending on how it's used and what polish/compound it's used with). I also find rotary's a little harder to use in areas where you have to reach more (ie hoods and roofs) because you have to stop it from spinning off the car to one side.

As for the pads...as far as I know, almost all of the pads can be interchanged between the two units (somebody correct me if I'm wrong).

Both units are random orbital.

including a very good description of the minor differences in the two machines.
Other than counterweights and accessories that come with each, they are identical random orbital polishers.

Nope, you had a lot of good info on the post, the confusing thing is the statement itself, you say buy the 7336 or the 7424 bonus kit from coastal? What does that mean?? Are you saying buy the 7424 polisher, but order it with the special kit that comes with it?? Or purchase the 7336 polisher, and order the special kit from coastal??

It means exactly what it says, buy a 7336 model from anywhere, or buy the Coastal Tool 7424 Bonus Kit...

The end result is the same - you get a PC RO sander/polisher machine, and you get a 6" counterweight. I guess I could have been simplistic and just say "a 7424 from Coastal Tool" but if you look on their website (you did do this right?) the only 7424 model they sell really is called the "Porter-Cable 7424 Bonus Kit".

Okay, gottcha! Had to go back again to coastal. Thought they sold them seperately as well, not as only one kit.

Okay, now what pads should I use, there are sooooooooooooo many of them out there.

sorry...was pretty tired last night after setting up for the car show all day. I was wrong...after closer examination (and listening to the pros on the board) both are RO styles. maybe I should go review the PC model line up some more
