Well here are some pics of us wet sanding
When wetsanding you should see a paste like substance forming, the sand paper will also start to clog with gelcoat. You can see it in these pictures, you can also see exactly where we have wet sanded to in some of the pictures. You can see it is white where we sanded and then you can see the yellowing where the old decals were. As you can see the yellowing is gone.
If you try this make sure you sand in circles, also rinse the paper when it clogs, also rinse the hull down frequently
Here is a before
We just did the first step tonight, we ran out of sandpaper, so we will come back to it and touch up any areas that need it and move to the next step,
As you can see almost all of the yellowing, or ghosting is gone. If you look at the pictures before you can see exactly where the decals where by the yellow all around them.
Here are tonights progress
When it dries it will look chalky and dull, then we will go to a finer grit, we have about 3-4 more wetsanding steps, then on the buffing. The only reason it looks shiny is there is water all over the hull from us rinsing it. It will look like flat paint tomorrow
