Moderate Boat Oxidation. Wetsand or Buff?
Hey guys/gals,
I inspected a 22ft Four Whinns H210 today for a new client of mine. It has moderate oxidation on the upper portion of the black paint. It's black with a white top. Wish I had photos to share, but that was my mistake. I'm trying to figure out the most efficient way to go about doing this.
Scale 1-10 (10 being really bad)
I would say its a 6-7.
1. Do I wetsand the gel coat down to eliminate the oxidation?
Or
2. Do I buff out the gel coat with my D/A and MF pads? (Keep in mind I do not own a rotary)
I'd like to see if I can get Mike's input on this!
Hope for some feedback.
Thanks.

Do a small trial spot with the D/A and let the results tell you which way to go.
Re: Moderate Boat Oxidation. Wetsand or Buff?
That was gonna be my first point of attack, utilizing a test spot to determine correct procedure.
Wanted to give the customer a couple quote options to work with based off how well it would be eliminated. I'll have to do a test spot first to determine that. I don't want to undercut myself, especially on a job like this, not to mention it is black.lol

With only a DA, wetsand (dampsand). If there is much oxidation at all you're just going to gum up pads like crazy and take forever with a DA. I usually use 3m Trizact discs. Start with 1000, then do 3000, then compound, polish (if needed) and seal. If you owned a rotary I'd say throw some 3m super duty on a wool pad and give it hell, but without that setup sanding is the way to go!

No rotary no sanding.Just polish and compound the best you can with the tools you have.If your client is going to pay you a considerable amount of money to sand then I personally would buy a rotary.And you will have one for the next job .

Very useful. I have Cobalt 242 that is 6 years old and has moderate oxid (6/7 out of 10)Tried using my flex 3401 with compound/ wool pad test spot (result = it will take me until Christmas 2019 to get it done). Looks like I either wet sand it or get a rotary n hit with wool/compound. Will do a wet sand with 3000 grit (least aggressive) using my 3401 and see what happens. Been reading Mikes book n am leaning toward sanding

Mike Phillips and I several years ago introduced his marine31 products over at thehulltruth.com as I was a moderator there, and the easiest, quickest, safest way that I found to attack gelcoat was with a rotary, a purple hybrid wool pad and a moderate compound. On Gelcoat that has been oxidized, I found an oconventional orbital, no matter what you did, wouldn't touch it. It would finish it fine, but It wouldn't do the heavy work.
Here is the how to , with pictures, from hulltruth…

forced rotation da, purple wool pad and marine31 heavy cut oxidation cleaner followed up by gel coat color restor by marine 31. i have a post under collinite 925 where i have before and after pics

Take a look at Meguiar's "Heavy Oxidation Scrub" (M-771). I think there may even be a vid over at Meguia's web site.

Reporting back on Cobalt mentioned above. I hit it with DA using 3000 sandpaper, then wool(marine 31 compound n polish,then light cut pad with same compound n polish,followed by wax n sealant. Don’t have pics but seemed to work very good. ( I had tried wool using rotary with heavy cut n compared to sanding , the sanding gave better results). Thanks for all advice.
