the PO of my boat must have beached it frequently because on both sides of the keel are a patch of scratches 3ft x 3ft. Can i wet sand those out using the procedures i got from the posts or is it a waste of time?
Of course you can only see it when it is on the trailer, but it bugs me everytime i look at them. thanks in advance. shawn |

Shawn, I'd have to say even without seeing them that they would be too deep to sand out. You may need to do a gel repair first to fill them and then wet sand smooth. A picture would help.

No, i don't think we will ever beach it again. The shore in Tennessee is not very sandy....more rocks
Here is a picture |

I dont' think that is from beaching the boat. The marks are high on the side of the bottom. If it was from the sand, it would be more on the bottom. I think it is from power loading the boat?

I agree with Greg. That's from the PO power loading while smoking something!! They don't look that deep so do a light wet sand and then buff. You won't get then all out.

should i start with 400 or 600 grit. i am assuming anything higher would not take the scratches out initally? I have read all the wetsanding posts.
sand......diamond cut compound......cleaner polish compound....and then wax. 3 pads...2 compounds and wax Right? |

Go ahead and buy 1000, 800, 600, 400 and 320 grit wet/dry paper. Try the 1000 first, then work your way towards more aggressive grits until you start seeing results you like. The less aggressive you go, the less sanding you'll do. When moving to the compound, be sure that each product you buy will remove the last round's scratches. Im nor familiar with the "diamond cut" compound or the "cleaner polish", but 3M Super Duty will remove 1000 grit scratches. A less aggressive compound may require you to sand to 1200 or 1500 grit before starting. Finish off with a good polish (like 3M Finesse-It II), then clean and cover with a good wax. |
