Deeper cut with more aggressive paper. Two-thousand grit doesn't do much for going deeper.

I would have thought the area under the decals would have been whiter than the (exposed) area around each decal.

Depending on how skilled you are you could start with a quick run at it with 600 to knock it down then move to 800, 1000, 1500 and then into compounding. BTW don't do any of these without a sanding block and water with a touch of dish soap in it. Ton's of how to videos on YouTube out there.

Depending how old your boat is you may never get it perfect as gel coat will yellow as it ages and the vinyl has probably been on there for some time. They do tend to blend over time when exposed to the UM so don't get too hung up on having it perfect on day one.

The boat is relatively new 2014. My sand paper skill level is pretty good just donít want to sand a hole in the side of the boat. Thanks for helping

Try 1500 next. Obviously if you jump in with 800 or rougher right away you'll have a pretty big project and yes, you will end up doing the whole side. Not a bad thing, but how much time do you have?

^ ^ this


To the original poster; the deeper the cut (grit cycle) the more passes you have to make coming out to remove the previous cut swirls.

Look for color on the paper as you go.

What about using an orbital buffer with a correcting pad and mild cutting agent?

A neighbors buffer from Griot worked wonders on my gelcoat where I had minor dock rash and scratches from inconsiderate guests. Iíve found the more patient you are the better the results.

Don't do anything yet. That yellowing may fade in sunlight. I'd let it do that rather than start cutting.
