What should I use for DA unreachable parts of the car?

[puma1824]

I recently purchased the Meguiars DA Microfiber System 5" as well as 3" backing plate and MF disks. What should I use for DA unreachable parts of the car to complement this system?

Any suggestion for polish, wax, applicator(s) for these hard to reach by machine areas? I'm thinking maybe Meguiars 105 & 205. Example: inside of BMW M3 mirrors, door handle recessed section, and other hard to reach areas. (see pics)

Thanks in advance.

First - very nice pictures!

Second - it is common practice to do some of these hard to reach areas by hand. You can simply use a 3" pad by hand if you'd like. M105/205 are great options.

Can also cut up some pads into squares... I believe mike has an article or a video (on YouTube) about this let me look around

Also you have to be careful using a DA on 3" pad. Because you can burn the paint on edges.

Its nothing like say the PC with a 6" pad where it pretty difficult to do, but not a 3" pad where it easier to do.

so if you have a gg6 or pc and put a 3in plate and 3.5 in pads on it, why is it easier to burn paint?

thank you

Since pressure is equal to force per unit area, The reduced surface area of the pad makes it possible to generate much more force at the face of the pad (this is assuming you are applying the same pressure in all cases), so theoretically it is possible to do more damage..... these small machines and pads are still extremely safe though.

I explained this concept in this thread: Hand Polishing FASTER Than Machine???

Good info on the 3"

Can you give us some additional details about how you can burn the paint with this pad on a DA?

Not sure I understand completely.

I agree

That is also...I suspect...why Meguiar's does not make the Xtra Cut MF pads in a 3".
The 3" regular MF cutting pad probably cuts more than 6" Xtra Cut, based on the concentration of power to the smaller pad.


I was curious about what ART meant by, "you can burn the paint on edges."

Get you some microfiber applicators for the door handles and inside those mirrors.

Paint is typically thinner near edges of body panels, on raised body lines, and that sort of thing, therefore those are usually the places that get burned/struck through.
