Wet sanding project started few questions to ask

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I started on wet sanding my 89 Ski Nautique and when I removed the stickers, it seems like it's whiter where the stickers were. 
Does the sun UV rays cause the white gel coat to turn darker? 
Has anyone else ran into that type of issue? 
Do I continue to sand till it's white or just live with a light cream color boat? 
Is there something I can use to get the white to match?

I started with 800 then went to 600 and now down to 400, the 400 getting the white under the sticker to match the exposed part, but it taking some time, thinking of using a power tool to dry sand the white with 400, but I'm not sure if I should.

The blue stripe was darker under the stickers and it's taking some time to get it to match but it's getting there, slowly and painfully. I only want to do this once, so any help is greatly appreciated.

	We just had the same problem come up a couple days ago. He sanded to the point where he started to see glass under the gel and could still see the shadow. Others have mentioned the same issue with shadows from the virgin gel color. I had the same problem with the transom on my Tique where the PO had named the boat with decals. I ended up having to re gel the complete transom. It's a combination of the UV and more so dirt getting down into the porous gel coat. Your solution is easy compaired to mine. I didn't have the option of covering the shadow back up with original graphics. When you put the graphics back on, they will cover up the problem. Don't try to sand them out too much. BTW, when I re gelled the transom, I had to use a slight "off white" gel to match.

	Don't sand dry either.

	pete is right and i ran in to that problem on mine as well.dont try to bring that white back out because u will sand too deep.all u can do is get it where its satisfactory and buff out.i did try dry sanding on mine and like gary said it was a flop..wet sand only imo.i started with 400 up to 1000 then used 3m super compound then followed up with 1500 and 3m medium compound then wax.not sure i really needed the 400 though i think starting at 600 for my application would have been sufficient.
