Summary: Speed boats often get swirl marks that can be eliminated with a high-speed buffer. Use a high-speed buffer on a speed boat with tips from a car wash owner in this free video on speed boat detailing.
"Hi it's Dow here at the Firehouse Detail Shop, we've evaluated the boat and what we found in cleaning here as we are going through how to detail your boat like a professional is that this boat has some swirl marks on it. And it's either from the factory that's just haven't been worked out yet. So what we did we got Gil here with his high speed buffer and if you see right here, this is the area we just took the swirl marks out, here is where we haven't done it yet. And I think you can see that, but it's just night and day from us here in this bright sunshine as we are looking at it. This side still has swirl marks this side doesn't. You can see how simple it is if you got the right equipment and Gil will you show us how that works. So he just comes in here, he is using a high speed buffer. He's using caution, not to get on top of the decals here. And that's great, thank you Gil. Come across here with your microfiber towel and look at that. It's got a mirror like finish. Now what I caution against is trying this at home if you don't have the right products. The right procedure you can actually make it worse, particularly on a black surface like this. This might be one of those steps that you leave to the detail experts and Gil, would certainly be that detail expert."
