While cleaning the boat down in prep for this weekends trip, I noticed an area, about 2" x 12" of orange peel effect on the outside of the coaming. Never noticed it before and cannot think what would have caused it. I'll add a pic later today (we have delayed our trip by a day due to weather.)

What's the best way to resurface that area? Should I just buff it out with compound and then wax it or does it need a gel-coat repair?

Here's a couple of pics, not easy to photograph. I have enhanced them a bit.

I have to assume it's a chemical issue although the Tarp is on between trips and we always fresh water wash the boat before covering it.

I've gotten littly tiny blisters under my vinyl bags where fresh water can be trapped. I would guess that is what caused it.

Paul, I have got a couple of these as well. I have not found anything to get rid of them. I was told, dont ask me who, but its a problem in the fiberglass.

Paul,
I have a similar spot, a little forward of your location.
I thought it was a delivered that way and I just didn't notice it before.

In my case, it could be gelcoat overspray from a factory scratch repair that was not buffed correctly.
It also could be a rough spot that the factory missed during buffing.
I had not considered this was a deterioration of the fiberglass.

I have not been keeping up with the waxing routine.
Do you wax very often and still have this problem?

Russ, we wash the boat down (fresh water) after each trip. We wash the boat with WM boat wash. About 3 times a year we apply NuFinish. I think we would have noticed this earlier as both of us have polished that area. (I <i>normally</i> do the wet areas and Peggy normally does above the waterline)

How do you plan on diminishing it on your boat.

Paul,
I was going to try buffing compound and wax, but if the top layer of the gelcoat has deteriorated, then buffing might make it worse.
You would think wax would smooth that out, but NuFinish should have taken care of that.

I have no idea. Try your dealer to see if they have a fix.
Since our hulls are 48 apart, this might be a problem they have seen.

I don't know Paul, that's a wierd spot to have blisters. Are you sure this isn't some type of glue over the gelcoat? I would try first paint thinner and then acetone to see if that can dilute it. Then buffing it with compound. If that doesn't remove it and you believe it's the gelcoat then what you can do is use an adjustable plunging rotor tool to skim about 1mm deep off the problem area. Then fill in with gelcoat and wet sand with 80,400,600 grit, compound, wax. I've repaired such a problem on another boat before with perfect results. Once it's done you cannot tell by touching or looking as close as you want where the repair was made.

If you need gelcoat I suggest going with a waxed marine grade. Waxed gelcoats will cure even if not covered by plastic. You can just spread it on as if it was plaster. I went with Industrial Plastics which matched the color on my 250 perfectly.

Assuming your boat is on a trailer, take it to a heavy truck (18 wheeler) dealer body shop. I used to work in that industry, and occasionally we would get in a new truck with an "orange peel" finish problem, usually on one of the fiberglass fenders. Somebody there can probably diagnose the problem. Most of the ones I saw were the result of a sloppy paint job.

Could the tarp have chafed it?

Has anyone brought this issue directly to Catalina's attention? If it is a manufacturing problem I would think they would want to get on top of it, especially if they know pictures and complaints are being posted on this website.

I'm pretty certain it was not there at delivery, we have worked on the hull (cleaning) several times and we're sure we would have noticed it.

Could be 'Tarp scratch', even though it looks like orange peel. Will try to buff it out and post result.
