Hi everybody,

i have a Meg DA 6 inch G110v2. I'm planning to buy a 3.5 inch backing plate (4 inch pads), wishing to gain more heat.

Will it be enough for Wet Sanding or for scratch that needs more heat?

Finaly, i'm not a pro detailer, just a crazy fan of :buffing:

Thx a lot

Heat is your enemy. The 4" pads will give you more correction though and will work fine with sanding disk as long as you don't go and electracute yourself

Can you feel the scratch with your fingernail
 
I wouldn't say heat is your enemy. Too much can definitely be a bad thing, but switching to smaller pads on a DA to gain some more correction power isn't a bad idea.

I don't have any specific corection / problem. It's just to ad more possibility to my detailing.

But i understand you're point: All i want is to add heat for small correction. And for sure, i know i must be careful whit heat.

Thx !

Thx. So if i well understand you're reply, it's a good idea, but i have to be very careful?
 
I dont want to be quoted for saying heat is a good idea. You can quote me that a smaller pad and smaller backing plate combo will get your better correction then a 6 inch backing plate and 6.5 inch pad.

And like Flash said above, practice first.

Heat is a nasty biproduct when polishing. Theres no getting around it though. I had never given it much thought untill Mike Phillips made a thread concerning this. The article made sense to me. I mean, I've always known if you leave your polisher (Ratary) in one spot to long you will burn thru, but the scientific reasoning behind heat, I had just never given it much thought

Pads & Friction

Friction is the source of heat.

The size or surface area does not directly affect the frictional force between two surfaces. Reducing the pad size will only improve the mechanical efficiency of the machine.

The motor of your polisher produces some amount of power. The larger the pad surface area the harder the motor must work. Now, most will say "it's only 1 extra inch", but when it comes to surface area and friction your really talking about an additional 10 square inches. Trust me, this is significant.

Surface Area - 5 1/2 pad = 23.75 square inches

Surface Area - 6 1/2 pad = 33.18 square inches

There is a direct relationship between the pad surface area and the polishers ability to transfer adequate power to the pad improving it's overall performance.
 
Thank you all to your answers.

I dont have a specific job to do. I just wondering if a smaller pad on a DA could help, on wetsanding for example.

I have a scrath on my Black Santa Fee, that dosen't totally disappear whit my Meg DA / Meg 105 / LC yellow pad. If I try something with the 4 inches pad, could it work? Could it be a nice try before WS?

I"m just asking, trying to have more ''tools'' and knowledge on my bag !! :)

Thx again guys (and grils!) you're very kind !!!
 
The thing with the scratch is you have to level the paint to the lowest point of that scratch to "totally" get rid of it, personally I would level it to a point to where you can live with it as I wouldn't want to risk removing so much clear coat you risk going through it along with Lessing your long term paint protection, just my 2 cents though
