First wetsanding got a question

[wgeorgio]

Well guys I did my first wet sanding job and need a little help. I kind was a little agressive and should have used something less aggressive like a 2500 grit afterward but i didn't. I just started buffing on it after wetsanding it once with 1500 grit. I started with dimond cut with a wool pad than worked my way down to machine glaze but i still have fine scratches from the sanding what could i use to get them out? Any help would be appreciated as usual. I took some pics ill post them soon.

M105 I think, and then follow up with 205.
I am not an expert on Wet Sanding or Buffing yet.
There may be a different option.
**Remember- Always use the Least Aggressive Method Possible**

u buff with rotary? or da?
83 with polish pad should do it, also when u did 105 with wool what tehniq u use, if the paste doesn`t brake down u will still have imperfections. i am not a pro , just my opinion

I used a rotary with the diamond cut I didn't have any 105 I want some though it seem like the stuff to have. I have tried my da buffer with some machine glaze and also tried some scratch x.

I do not think Scratch X will cut it.

Re: First wetsanding got a question

When wet sanding, you usually finish sanding with something higher than 1500 (1500 first to knock down the peel and then 2500 or so).

It's probably a better idea to sand the paint with a higher grit (2500) and then polish out the marks. If you just do a bunch of passes with M85 and a wool pad, you may remove more paint than just sanding with 2500 and removing the marks.

Please, do a test spot. Sand the area with 2500 and then remove the marks with M85 and a clean wool pad. If that removes the marks, great. If it does not, then use a more aggressive paper (2000) and follow that up with a less aggressive paper (2500 or 3000). Then, try to remove the marks.

Re: First wetsanding got a question

You need to finish with #2000 or higher, I finish with #3000
Then a wool pad on a rotory and M105

Re: First wetsanding got a question

M105 would probably be your best option. I used to use #83 for years before M105 and it works good. You just have to work #83 a few times to completely remove the sand marks. You should definitely use some 2500 grit with plenty of water, detailer or soap. That will help remove an scratches in the paint and leave a nice smooth "haze" that you can buff off.
