Hey Guys, just wanted to make sure I'm doing this right.........got a 2010 , washed it good today and clay barred it, it was never clayed before, while doing the baggie test are you supposed to feel a little bumpy or Nothing at all.

I'm thinking since this has never been done before on the car I might need to do it a couple times.

So the question is are your supposed to feel small bumps or do it until you feel nothing.

Don't know how to do a baggy Rich
 
Yo want to feel nothing at all, if you feel bumps then keep claying

Ahhhhhhhhhh, maybe I should add a little more info, the clay bar itself didn"t show much dirt one way or the other, and all I did was the top, hood, and back lid............it was getting hot out today, and I think the beer was getting to me also. LOL

You will never get all the little bumps out unless you plan on wetsanding no matter how much you clay. The baggie test will drive you insane.
 
^Yes

You could be feeling tiny chips and other imperfections on an 2010 vehicle.

If you are using a clay bar and it's not showing much on the bars surface, then I would be content.

You'll always feel rockchips, pitting and you'll never get 100%. The idea of the clay is to remove above bonded contaminants. You'll never get 100%.

The idea is to create as much smoothness as possible before going onto the next step. Every part of the detail process is a concatenation. You cannot have gloss without smoothness.

The baggie test is normally done before you clay to get a measurement of just how contaminated the paint is, the after test is to see if there was marked improvement. If none, then refresh your technique or look at the grade of clay you're using. But keep in mind, anything other than "fine" will more than likely result in having to machine polish after because the risk of marring the paint goes up. Mileage may vary.
 
Never understood the requirement for a baggie. I trust my fingers running over a wet, lubricated surface as sufficient. I tried a thin baggie once (1.5 mil vs 4 mil for the freezer bags) and it was no different than my finger in terms of sensitivity.
 
I gotta say 1 thing, I'm new to this forum, wow, cant believe the tips I'm getting this fast..........got a new PC awhile back, gonna kick some butt on this car now. Thanks again guys

Wow I have done the baggy test for 4 years and never had a problem.

Run the test, Speedy Prep Towel, run test and repeat.

If you can see pitting or chips of course they are going to make the grinding sound because they are not smooth.

I have black stripes down entire hood, roof and trunk.

These are not covered in clear coat so they make a noise when I clay over the edges.

I'm not intetested in the edges, I want the surface to be silent (clean).

Oh boy, LOL, one last stupid question, how do you determine what grade of clay you have,..........I just bought the Mothers clay kit..........no mention on the clay, fine or what.
