Using Meguiar's 3000 grit Unigrit Finishing Discs

[kerenzv]

hi ,
i am new at deatling and just strated before two weeks ago i read a lot at this forum and also bought the complete guide for show car shine and learn a lot both from the forum and from the e-book, but today a selling agent of proudcts for car care and deatiling came to my work and offer me to buy the meguiaers dual action with the 3000 grit and told me that evryone now is using this method of buffing the car with the 3000 grit no matter what is the condition of the paint and using meguiers 105 and then meguiars 205 for finshing .
my question is if i can work this way because according for he was saying its take only two hours to do a car while it take me about 6 hours to do a car , i didnt find this in the e-book or at fourm so this way i ask if this is a good way to work on a car
or if it can destroy the color of the car and i would have a peobleam of fixing it?

I wouldn't say "everyone" is machine sanding cars.

If you've read this forum at all you know that the factory paint on new cars is very thing and sanding should be a last resort, not the first step.

It could be that his point was that machine sanding is an "option" as compared to grinding with a compound and a wool pad on a rotary buffer and this is an option but you shouldn't be sanding down every car you buff out and it's going to take longer than 2 hours no matter what you do.

Heck just doing a GREAT washing job takes about an hour when you include washing the wheels and tires and also drying the car.


Also keep in mind,

Sanding removes paint
Compound no matter how you do it removes paint
Polishing removes paint


When working on factory thin, hard paint, it's pretty easy to at some point in the process and in some place on the car strike-through the clear and expose the color coat.

Ouch....

More reading.... good question though.

If you see this sales guy again, ask him to join our forum and post his recommendations.

Are you working at a body shop?

This sales rep must be in the business of selling paint jobs...

I wonder if he said "everyone uses 3000 grit now" because he meant that takes the place of using clay?

I know a shop that does this.

^ If substituting it for clay then it's wrong

I have 3000 3M i've had it since January and still have't used it, but 3000 does have it's place.

Clay I alway use
And a combination of light polishes/medium polishes and compounds depending on the situation, and pads.

I just wet sanded a little BMW 2002.
And not everyone is doing this and not every customer will pay for wet sanding.
I sanded/corrected for 16 hrs. That's a lot of money and my "mom taxis" aren't going to pay my wet sanding rate.
So no, not everyone is doing this.

Weeks more seriously but still only doing friends and

According for what he said he just came back
From a shop that he sale them the meguiars dual action
And the unright 3000 and he did a black car
In just two hours with this , and that the car turn
Out like new.
I saw at the meguiars forum a post with this
Way of work and they also say that it's a fast way to work

Does using a meguiars 101 or 105 with cutting compound
is less aggressive then the 3000 grit?
