Post subject:  Returning shine to hulls
I recently purchased a used 16, and I was given some 3M Fiberglass Restorer & Wax. I purchased a 6" buffer and started to work on a 1x2 foot section. After about 10 minutes and two applications, it doesn't seem to have worked as well as I have hoped.

There still seems to be alot of dark brown/green staining on the hulls from sitting in the water.

Should I have more patience or should I move to using something else?

Thanks.

Try a toilet bowl cleaner with chlorine (if the hulls are white) to remove the stains. If their is heavy oxidation wetsand with 320/400 & 500/600 then buff.

The boat is actually your old one:), so by "sitting in the water" so I don't think the problems you mention are the issue. I was just commenting on where I believed the stains to come from.

I'll try the toilet bowl cleaner. I guess I could take some pictures to show what I'm talking about.

Sorry Mike, notice I just edited my post AFTER I realized who you were :oops:
That color is Kansas blue! Wetsanding is probably necessary if you want her to shine again. Do the deep clean first, otherwise you'll sand that grunge deeper in to the gelcoat.

Brad,

Has anyone tried the Boat Scrub yet? If it in fact cleans AND "reoxidizes" in one step that would be the cats' meow. :)

Would be curious if your rep knows how many bottles it would take for a 16 and how much is this stuff?

we've used the boat scrub here in here shop on some Hunters, it cleans about anything.

I just spoke with them Boat Scrub will remove the oxidation, coverage is about 200 sqft, They got real technical with me on how to do it best I am going to attempt to repeat what they told me.

Apply Boat Scrub, spray Boat Clean Plus on it and it will force the boat scrub into the pores of the fiberglass, something about having smaller molecules way over my head. Once it is all clean apply a Boat shine to seal everything in.

I am sold on the products which is why I brought them into the store, still in the process of getting it all on the online store. We have some on there now, should have it all wrapped up within the week.

Don't know about the brown stains, BUT my Hobie 17 had the green slime/mold from four years on neglect outside. A $1 (at local grocery store) can of Bon Ami and a hard bristle brush were all I needed. Even made a paste out of it (let sit 15 minutes) to get out rust stains. This was on white hulls. They came out great.

I used bar keepers friend on the top of the hulls and the vinyl and it works wonderful. I gave it quick try on the sides of the hulls and it didn't even touch the stains.

I'll try the paste and let it sit there for 15 minutes. I already have the bar keepers friend so it shouldn't hurt to try it again.

I just wanted to say that I tried using snow bowl cleaner on the hulls. I'm amazed how clean they got after just wiping them down. Good thing too, as it was much easier than I thought wet sanding my entail.

The snow bowl cleaner seemed to work much faster than the barkeepers friend paste on green/brown staining.

Thanks for the help. I'll have to post some pictures when I'm finished.

Whats the best way to get my chalky yellow tops back to something a little more shiny? The white hulls seem to be pretty good...
