Hey guys,

I have a 2 part question here. I am going to be wet sanding a truck this weekend and polishing it out. In the past I have used a wool pad and rotary with M105 to remove sanding marks and then M205 on Griots 6" buffer with foam pads. My rotary buffer has bit the dust and all I have is my Griots 6" buffer and numerous Buff and Shine pads. I need your professional opinions whether or not the foam pads on the Griots will be able to remove the 2000 grit sanding marks with either M105/205?

Is M105/205 the way to go or would you recommend HD Cut, HD speed/polish? I really like how HD Speed is easier to work with and virtually no dust but I have no experience with HD cut. Is it as good as M105 as far as the cut?

IF the Griots 6" and foam pads will not remove the sanding marks then I will have find me a rotary by the weekend. Thanks in advance for all your help.
 
IMO You will have no issues removing the sand marks with your GG6. I would use the orange foam pads with the 105 and then the white pads with the 205. I wet sand on occasion and that is what I do. I will use my main DA the Flex 3401. I have used my Pc7424 XP too and that DA is not as strong as the GG6. I say go for it!

PS: If you are more comfortable using HD that would be fine too. I have never used HD products so I cannot comment. I have used 105/205 and they are a great product.
 
Why not sand down to 3000 to lessen the compound? If you do, your Griot6 will work fine.
 
never actually thought about using 3000. I may have to give it a try. thanks for your advise.
 
I would guess it might depend on how soft or hard the paint is.
 
I would recommend Menzerna FG400, great product, will remove the sanding marks and leave a near mirror finish with the correct pad.
 
Hey Guys. Just an update on the results. I wet sanded with 2000 grit paper and then used M105/M205 on Orange/Blue Buff N Shine foam pads with GG6. Results were excellent. All sanding marks removed and polished out. These results were just as good as it normally is when I use the rotary with wool pad with the M105 and finish with the GG6 and M205/blue pad. I am very happy that the rotary was not necessary since it was broken. Now, just to test the waters, I used HD Speed with Orange pad on a small section of the truck and it removed all sanding marks. I was shocked than an AIO was able to remove 2000 grits sanding marks. I have always been a huge Meguiars fan and now I am becoming a 3D HD fan.
Has anyone else gotten great results with HD Speed or any other AIO's??

Did you wipe the panel down with a solvent after to ensure they were actually removed after speed?
 
I didn't wipe down the panel afterwards with a solvent. I guess this would determine if the polish or wax in Speed is just filing in the scratches or if product actually removed them. What type of solvent would you recommend to wipe the panel down with?

Im not Chad but I would recomend a wax and grease remover. Prep All is a good one. Spray on, let dwell for approximately 15 seconds, wipe off. I would repeat that a couple times on the same spot. That should get you bare paint.

Is this fresh paint?

IF this is fresh paint, like less than 30 days old I'd be careful about wiping it with solvent.


Years ago I wrote the below article, (if you read it I state I NEVER wanted to write it but no one else would).

Note the FIRST paragraph and the color of the text for the heading


How to Mix IPA for Inspecting Correction Results


WARNING
Do not chemically strip FRESH PAINT. Fresh paint has not fully cross-linked, dried and hardened. Introducing any type of solvent to the surface and allowing it to dwell could have a negative effect on the paint.


If this is factory paint then I agree that you might want to strip a section to make sure the results you see are the true and accurate results.

If so... good job!


:)

The oils and protective ingredients can mask some light defects (As would be the same with most any polish) so it would be a good idea. Mike makes a good point too about fresh paint.

On the left Speed was quickly hand applied like a wax, so as you can see it will hide some stuff. A wipe down should remove it though.

 
Thanks so much for all of the responses on this. I am just amazed by the knowledge and talent that everyone on this forum has. You guys have already taught me so much about the detail world. Thanks Mike for all the information and willing to share. I find myself like a sponge just soaking up all of your videos and posts, just trying to learn more and more. Thanks Chad for taking the time to respond as well. I viewed your website and you do unbelievable work. Not to leave anyone out- thanks again
