Need some advice. I've done many paint correction jobs with my rotarys and DA's. I'm working on the 2000 corvette currently and my flex 3401 is leaving nasty da marks?!

Using m105 followed by m205. I've tried many other products and still get the same result. What the heck is going on? Using a soft black polishing pad with the m205.

Car looks beautiful, but under my light it looks like garbage. Any help or advice would be greatly appreciated.

I hope you mean 105 followed by 205 otherwise that's your problem...
 
What color pads are you using? Do you have any polish other than 205. Kind of strange because Corvette paint is known to usually be hard. The only thing I can think of is do another test spot, start with 105, make sure all that is left behind is a little haze. If that paint is extremely hard you may not have removed all the defects with the 105. Then when the paint looks good...or only haze try the 205 again.

Your saying gray scale. I'm seeing swirls in the paint, I'm assuming the gray your talking about is probably DA haze...does that sound right? Or is there something I'm missing in the picture?
 
The first part of your post didn't sink in when I read it the first time. I didn't realize you were that experienced. Have you done a few Corvettes?
 
What pads are you using? Perhaps try finishing out with a different DA instead of the flex.

Lake County pads, orange and white followed with black. By Grey scale, yes I mean swirls. Looks nasty.

I found the flex did well for initial polish, then change to rupes for finish polish.

Another thing I see is that you originally said you did 105 with a black lc pad.........
 
Does the paint seem hard? It really looks like the 105 didn't get all the defects. I had a black Infinity I ended up having to take a rotary with wool for the first cut to get the defects out. I still think I would try a test spot with 105 and see if there is any improvement in the swirls. Those swirls don't look like they were introduced by the DA to me.
 
Another thought is that maybe the paint is on the very hard side and you would need to go with a more aggressive approach
 
Have you considered making more that one pass with the M105/orange pad? Maybe the paint is so hard that it will take more than 1 pass of M105/orange pad to get the defects out.

I may be misunderstanding this, but could you be meaning that the M206 and white pad (or black pad from your initial post( is creating defects?

105 is hard to work with,you need micro pads for that car.Ive done 40 corvettes for a dealer in town.Here is what I had success with,fg 400 on a micro pad then HD speed with a orange or yellow foam pads topped with jescar.Or 205 only on a cutting micro pad then sp3800 on a yellow foam.If you're looking for newer products sonax will bang that out in one shot then top it.you could be dry buffing with 105.
 
I doubt its the Flex that is leaving a bad finish, have done numerous paints with a Flex and the finish while not as amazing as the long throws still always finishes darn well. I suspect the issue lies in one of two things. Either you didn't get the defects out from the initial compounding stage or the 205 is leaving behind marring which I have seen happen on some black paints and 205. I think its hilarious that people are thinking the Flex is the culprit.
 
I think the promblem lies with the 105.New sonax products make it easier for promblems like this.one product one step and void out all the confusion with different pads and such.
 
GSKR which Sonax product is it that you recomend for hard paint?

Every time I think I'll do a test spot with 105, I say "what was I thinking!" Most of the posts on this forum that are related to poor results have to do with 105 and or (dare I say...) 205. Both are very good, don't get me wrong, and work wonderfully... under the right conditions and paint. I've had great success with 205.

But really the go to is BOSS Fast Correcting Cream, Pinnacle Advanced Compound. I also had great success with HD Adapt 501 & 502.
I also used the Sonax 04-06 and really liked that as well.

I recently did a 16 Corvette with Boss Correcting Cream, and Fast Correcting Cream in some spots for spot buffs...

You need something with a longer work time. Also, did you prime your pad? How many section passes did you do? Did you do a test spot, one with 105, then another with a different compound (with a different technology) to compare the diff? I perish the thought if you did the whole car w/out a test spot and realized after 5 to 8 hours you didn't like the results....
 
I did one step on a newer Camaro. The swirls looked very light but were fairly tough to remove. Microfiber pads gave me the best results.
 
Thank you very much sir!!!

I wish their new ones were on the polishing chart, I have a hard time figuring out where they fit in.
