This is part 2 of the sanding series from Evan of Evan's detailing and polishing. This video breaks down the differences between rotary sanding and da sanding. The differences are huge and very significant but the outcome can end up very similar. There isn't really a right or wrong way to sand. It is mostly personal preference on the user. In our shop we mix the two different styles and end up with something completely different. If you want to see the full process we offer a training course on how to sand and polish both aluminum and stainless. Stay tuned for the next video where we physically show you how they are both used and applied to aluminum.
All of these products use in this video are available at www.amazon.com/shop/metalpoli... or by the individual links.

I can definitely agree that one should learn to sand with a da and not a rotary, took me awhile to figure out why I was getting those Crescent shapes and swirls in the metal and I started with an 8000 RPM angle grinder

Mirka Deros electric da is an awesome sander as it should be for the price around $600 but it out performs my Ingersoll pneumatic hands down. The pneumatic kept the compressor running constantly so the offset in electric usage helps justify the cost. I always said if I find an electric equivalent to an air da palm sander I'd buy it, guess I had to live up to my word.

Can you use a variable speed polisher to sand? And just buy the add on? Or do you have to buy the whole sander for rotary.tia
@EvanStegerMetalPolishing
@EvanStegerMetalPolishing 3 года назад
Yes you sure can. goshineon.com/shop we do sell the attachments.

I thought there is a difference between Rotary sander vs Random Orbital Sander vs Dual Action Random Orbital Sander. Main thing being swirl marks left behind by each. Which brand & model of random orbital sander or DA random orbital sander do you recommend?
@EvanStegerMetalPolishing
@EvanStegerMetalPolishing Год назад
That's exactly right. I use the Makita DA. I prefer it for the tight finishing pattern. Makes it easier to polish in my opinion. Here is the link for the sander I use. amzn.to/2SxCY3r

Did you not make the video of you using the sanders? I been thinking of getting a electric dewalt sander for body work since i dont have a big compressor. Would like to see the video brother!

What do you recommend to take the paint off a bike frame ?
@EvanStegerMetalPolishing
@EvanStegerMetalPolishing 3 года назад
No idea. I don't take paint off anything. I do know sandblasting ruins it. But I just don't personally do any of that so I don't have a proper answer.

As per Hisaw's comment .. are random orbital and dual action the same thing?
@EvanStegerMetalPolishing
@EvanStegerMetalPolishing 2 года назад
Not really. Dual action has a different pattern internally than the random orbit does.

What are some good brands of DA sanders? DA sanders do not seem as prevalent as RO or Rotary.
@EvanStegerMetalPolishing
@EvanStegerMetalPolishing 2 года назад
I have them that I use tagged in the description. I like Makita.

Question: is a random orbital sander the same as a dual action? Thanks
@EvanStegerMetalPolishing
@EvanStegerMetalPolishing 19 часов назад
No. They are two different rotations. Dual action is more aggressive.

@johnny0454 2 года назад
Are "dual-action" and "random-orbit" the same thing?
@EvanStegerMetalPolishing
@EvanStegerMetalPolishing 11 месяцев назад
No a random orbital can be a type of DA polisher as it's just another pattern of movement.

What speed do you recommend for sanding with a rotary? I assume you use 5" sanding discs. Edit: You answered my question later in the video. Thanks for taking the time.

Some errors here. On your right is a DA sander ( red sander ) . It has rotary action and orbital action.

Which one is better electric or pneumatic?
@EvanStegerMetalPolishing
@EvanStegerMetalPolishing Год назад
I prefer electric, air is inconsistent which makes it more difficult to control pressure and speed
