Why #80 breakdown too fast with rotary??

[Vincent]

I wonder why #80 breakdown so fast after just few overlapping ? This is what I did, set to 1200rpm, using 8006 pad , prime the pad and follow the procedule as shown on the Meguairs video working on 1' X 1' area. Just few overlapping to complte the working area and the product already brokendown. What is that so ? Help me please ?

It's designed to break down fast. Nothing is wrong. If it's not getting the defects out fast enough or effectively enough for you expectations then you'll want to switch to a more aggressive product, such as M83 or M84.

Hi Vincent, didn't know that you're a rotary user! Zey told me before that about 9 or 10 seconds(if i'm not mistaken) is all it takes for a rotary to break down M80, much faster compared to a PC.

Hi Fishbonesken,
Oh ! I just got my fisrt rotary yesterday, try it out then found that the #80 was brokendown so rapidly compare to use with DA polisher. After tried out small area and started to rain. Just check to area under sun light, suprisingly all the swirl mark is GONE . Zey didn't told me about that so I post the thred. Thanks to Mike so much for your explaination, I thought something went wrong or my technics didn't right. Now I can continue to finish the whole car. See you...
P/S : Have you check your email ? Got some massage for you...

Yup, esp our weather here in Malaysia, #80 breaks down rather quickly.

Be sure to post in the show off forum after that :P

Hi Sherwin,
I browse thro youe website and found you are using a rotary to buff your car, are you using the 5" backing plate ? Where did you get it ? I was looking for it.

Vincent,

I'm using the Makita 9227C rotary buffer together with the MG W-64 5" inch backing plate.

The backing plate can be purchased from the MG distributor here, Hypercoat in USJ1.

Oh ! I see. Thats good if can get locally. I can't get it here in Penang, gotta order from Meg agent, take weeks to deliver . After few hands, it will cost a lot, BTW how much does it cost ?

This is just from my experince only...

If the pad is brand new OR heavily saturated in product, it will act almost like a sponge and make buffing difficult. Make sure you are cleaning the pad frequently. I use a towel (per Mike Phillips) wrapped against my finger and push it against the spinning pad to after every one or two sections.

You have to use the right amount of product, too much and it spreads, too little and it goes quick.

It is weather dependent. On a mild day, #80 will give me several minutes of play time (though it probably breaks down quick, it leaves the oils behind) where as on a humid, hot day, #80 is gone after 5 passes or so.

Don't use pressure on the machine, let the machine provide the pressure. If anything, on your last couple passes slightly (but evenly) "lift" the buffer to lighten the pressure.

When to the polish goes clear, I always slow the RPMS down and make a couple light passes with little to know pressure. I friend suggested the technquie and it has allowed me achieve hologram free results on some paint finishes...

Examples.

Before



After one pass of #83 (I have found #83 breaks down much cleaner with a rotary and can often leave paint ready for an LSP via rotary vs. a P.C. where you may get a haze).



Outside, looking for hologramming)



Here is C6 Corvette.

Before, you can see the swirls and if you look at the edges of the reflections of the UV light, its dull and fades into the background...



Now look at the edges of the bucket that holds the UV light. Razor sharp reflections and the paint is darker and clearer, not to mention the swirls are gone. This is after one pass of #83. I went right to my LSP after this.

Hi, TH0001
Are you using #83 with 7000 pad or 8000 pad for one pass ? What rotary speed you set ?
I was using #80 , 8000 pad with 1000rpm, need 2 passes to completely remove swirl. If only need 1 pass to complete the work, could have save half of my time.

Re: Why #80 breakdown too fast with rotary??

By one pass, I mean one application, usually about 4-5 "passes" over the same area.

Sorry for confusing you with my words. Ya, I meant 1 application with few passes to get to work done rather then few applications for the same work. What speed and pad do you use for the application ? Thanks
