Heavy Oxidation?

Hello,
I have some oxidation on the back of a 1992 Prostar 205. The first pic shows a spot where I rubbed the gelcoat for about 20 seconds and rubbed it pretty clean. The second pic is where I removed the decals to show the difference between the oxidation and what the original gelcoat is like. Here are my questions:

Is the oxidation heavy enough to require wet sanding? I would have to wet sand the transom and about 5 feet on the sides.

Will 3M Perfect-It or Finesse-It be enough to bring this back to original color?

I would like to polish this to like new condition so any thoughts and suggestions will be greatly appreciated.

Thanks
Scott

That in my opinion will need to be wet sanded and then buffed and polished. Should shine like a new penny after that.

You will definitely need to hit that with 3M Imperial compound with a 100% wool pad. Try that first before you wet sand. But I am guessing that wet sanding is in your future. Don't let the wet sanding scare you. Take your time and do it right and the sanding scratches will come out easy.

Here is 3M's take. They say the best way to see if you can skip the sanding step is to test compound. I think they mean testing with a polisher, like say a rotary polisher and wool pad, not some hand rubbing.

3M Marine Professional Gelcoat Finishing System

According to this video, Finesse It II polish is for light oxidation only, and the other product you mention -- Perfect It -- is even less aggressive. The Imperial rubbing compound they use in this video is more aggressive than those two but, I think, less aggressive than the 3M Super Duty many on here have used and BrianM has in his process described in the first post here:

I found them all on amazon, I think other have too. Before I could purchase a sales rep from the local paint supply store came in and said he carries that. If you don't want to do amazon try commercial paint supply stores.

After quite a bit of shopping online and locally, I've gotten most of my compound, polish, and wax, including 3M products, on Amazon (both directly from Amazon and from third-parties selling on Amazon). I've been getting my 3M wet/dry paper from an auto paint supply outfit that has just a few stores in my area. I think 3M has a big presence in the bodyshop and professional detailing markets, so outfits supplying those guys have their products and so do some outfits more geared to consumers. For pads, I'm using Lake Country purchased online from Autogeek (they tend to have sales in weekends), so I haven't sourced 3M pads, but I would think you could get them from the previously mentioned sources for other 3M products.
