We bought this 2006 260 Sundancer in May and noticed it had a lot of yellow - brown stains around the bow deck. Our detailer said he could remove any stains that were on the deck (site unseen) but when we had the boat delivered to our slip, the stains were still there. Any ideas as to how to remove them and what they are?

No idea what they are. It almost looks like the previous owner tried to apply something to the anti skid to make it better, and it failed. Have you tried soft scrub, rubbing compound, or a cleaner like Spray Nine or Tilex yet ?
 
Sorry to say but it is a Searay problem.:smt021 I have on my current one and had it on 4 of the 7 Searay's. It is from the mold releaser which was not done correctly or remove. Mine was not as bad as yours but it always shows up where the non-skid meets the smooth surface and on the high peaks of the fiberglass. It takes a year or two to come out.

The only way to get it out is wet sand and Polish. Two of my friends already had Searay pay for it to be done.

PM me on this. I have yellowing on the foredeck and swim platform. Your picture is hard to make out. I have some pics that I can send to your email if you like. They are large files.
 
I had the exact same problem on my last boat, '06 240 DA. I think mine was caused by poor surface condition. I scrubbed the hell out of it with soft scrub then applied 2 coats of wax and that took care of it.
 
Half Off I tried that on a few of mine it works some times depends on how deep it is. Had it every come back? I'm told it comes from a chemical reaction from the mold releaser.

You may be right John, I didn't keep the boat long enough to find out if it came back. I traded it after having it only one year.
 
I guess its worth trying a test with the soft scrub...
 
It is mold release compound and rubbing compound with a known size abraisive and a slow rotary (not orbital) buffer is the only way to remove it with consistent results in an area this large. Soft scrub may eventually work on small spots but it may take until you start drawing social security and will leave a haze in the gelcoat.

There are varying opinions as to the cause of the yellowing......deck pulled from the mold too soon, too much mold release on the non-skid area, bad gelcoat, bad mold release compound, deck not cleaned properly, etc, etc. Sea Ray usually accepts responsibility for the yellowing issue so you really should take the boat to your dealer and ask for help.

Good luck with it............
 
Frank you are 100% correct this is what I know after owning 7 of these, however, I was not able to get mine out with compound.

I have seen a couple of bad cases where Sea Ray ended up sanding the deck and shooting new gelcoat on the non-skid.........and I'll have to say, those 2 boats had the best looking fore decks of any Sundancer around since the non-skid was not as aggressive and was easier to maintain after the new gelcoat was applied.
 
I had the local SR dealer send their gelcoat guy to look at the boat. They submitted the findings to SR and they turned the repair down. I have a case opened with SR directly to appeal. That was over 4 weeks ago and have heard nothing. Time to call. My dealer estimated approximately $1000.00 to repair.

Hey John, How did you friends get Sea Ray to pay for the repair? We contacted our service manager at Marine Max, and he is going to ask on Monday. Did you friends contact Sea Ray directly? Someone knows about this problem as quite a few of you that have responded have the same 2006 260DA as us. Thanks for all your help! :thumbsup:
 
Anyone heard of or used this stuff to get the stains out? http://www.jamestowndistributors.com/userportal/show_product.do?pid=2486 From a Google search: Yellow stains in Gel Coat If you find that your Gel Coat is turning yellow at the water line, look for a product called Y-10® at your local marine store or chandlery. It is a blue jelly goo you just brush on, wait a while and wash off with soapy water. Amazing stuff! And from one of our readers; "I note among the useful tips on your web page a recommendation of a product called Y-10 for removing yellow stains from the gelcoat around the water line. No doubt it is a fine product and does the job, but for several years I have followed the suggestion of one of my fisherman friends in downeast Maine and have used a product that is very effective, readily available, and probably cheaper than Y-10. You won't find it in your yacht chandlery. But go to the local supermarket and pick up a bottle of Lysol Toilet Bowl Cleaner. Put it on with a damp sponge or rag, leave it for five minutes and wipe it off with a wet sponge or rag. As with any powerful cleaner, you might want to wear rubber gloves, and you should be careful not to get it in your eyes. I use it on my Bridges Point 24. It works." sent in by Kent Mullikin

Don that may work but it sounds has this will clear up water staining. What we speak about it a chemical reaction. Don't know if this would work. Would be nice if it does.
