Wetsanding

[ultrajim49]

Those who read my review of the BO6040 ( http://www.autopia.org/forums/showthread.php?s=&threadid=16906 ) know that I have a hood to test things on.

The center part was my test area for wet-sanding.I have never done this before, but learned a lot since then:up .



The sanding paper = Picture 1:

Picture 2: after sanding:

I let the sanding paper soak in plain water for a half hour.

With a sponge I wet the area to be sanded, as I was sanding, the surface dries, therefor I held a spritz-bottle with a soapy mix(just like claying) to wet the area again.

I folded the sandingpaper around a kitchen sponge to get a better grip and for better distributing the "force".

I think a rubber sanding block would have been better still, for a more even finish.



Picture 3:compounding:

After drying the surface you need to compound to get the sanding marks out: 3M fine cut with wool pad (Makita-wool pad)

As you can see there is a haze left by the compound.

Perfectly normal.



Picture 4: polishing:

To get the compounding haze out you need to polish: 3M machine polish, and Megiuars polishing pad

the apearance improves greatly.

Glazed this hood starts to look like something "Autopian", allthough you can clearly see scratches wich go straight through the clear:sosad



Picture 6: the result after waxing:

After Meguiars Gold Class paste wax: shows that imperfections (scratches) are not hidden with waxing:D

That`s about the best I could get that hood





What have I learned?

I have learned that wetsanding isn`t something to be afraid off, providing you use the wright steps in the wright order, this is VERRY agressive , and will surely take alot of clear away, but sometimes something as abrasive as this might be nececeary(sp?)

cvcaelen: did you use your Makita orbital to conpound, polish and glaze the wetsanded areas? I always thought you needed a rotary to remove sanding marks.



theveed: where`d you get fine grit sandpaper here in the phils?

[jerry@robs]

Green: You can get them in car paint stores. Simex has them as well but of course they overpriced it a little, but it`s still cheap at P20 a piece... compared to the outrageous UniGrit papers.

Yes, I did,



the Makita has not the speed of a rotary, but with it`s forced rotation and a 750Watts motor(you can put pressure on the orbital) and some time, it works

Mind you, the hood was BNR(beyond normal repair:D )but I could get the most of the scratches out.

The sanding marks were completely removed with the compound

Machine polisch could be buffed to a high shine.



If only the freezing would stop so I can give my car "the treatment"

interesting thread!



I have lots of swirls that I couldn`t get rid of with DACP,#9+pc.

I wasn`t happy with the result of DACP and wondering if I should try wetsanding this time. Do you think it`ll work? I`m too scared to use wetsanding :(

Try using 3m medium cut compound. I have gotten good results with it and yellow pad on pc. This is the most aggressive product I have tried with the pc and it handles it fine. I don`t know how much more aggressive you can get with a pc but medium cut is not a problem at all.
