Say you've noticed what appears to be spider webbing of your clear coat. Very very fine cracking, not like its coming off in chunks or anything. Definitely not scratches, but you can kind of feel it with your fingernail. Its not even easy to see to the untrained eye (I've trained my eyes well )

The cracking kind of follows the waterline angle when the boat is on the launch ramp and is almost limited to that same area. i.e. no cracking on the deck, bow, hatch, hull sides, etc. Those areas are pristine. Only on the rear quarter sides and transom where the water meets the boat on the ramp. Imagine the water splashing the hull on the ramp. No cracking above or below that area for the most part.

Assuming there were no errors made in the application of the clear, is it possible that the temperature shock could cause this cracking?? i.e. 115+d air temps (and possibly hotter gel/clear temp) and what, 68-72d water temps (Parker water is always cool devil).

Assuming it was temperature shock that caused the cracks, is there a clear that is impervious to this situation? Or will all clear crack under these circumstances?

If it was an application error, please ignore this post.

And for the record, this is hypothetical sphss

"IF" its on a certain boat..I'd be callind 619-442-0300 at 9:01am this morming. You want to get that looked asap.

IF it was a certain boat, I'm pretty sure I would have already made that call...maybe more than once

And did you not receive the answer you were looking for, about "said certain boat" ??

May be able to fill the cracking area's with matching clear or color...sand and buff?


But WHY is this un-named boat cracking up ???

I thought I was the one asking the questions?

Quick !!!!!!! Sell the boat

If it was my boat, I'd have it fixed before I sold it.

I hope that wasn't a hit on me. I never saw any problems with the gel, if your talking about that boat.

No it wasn't. If it is this boat I'm certain I would have seen it. I damn near looked it over with a microscope, and so did my wife :|err

Hypothetically speaking, if my boat had this problem today, I wouldn't sell it in its current condition. I would have it fixed.

What your seeing is called laquer check. It happens in enamels, and eurathanes as well. Filling it with additional clear will simply cover the problem. It will come back. The only way to correctly fix it is to sand it off and re clear it. Its usually caused by sub par material, but can also be caused by mis application. It was a big problem up here for many years, due to the elevation and the effects the uv were having on finishes. If its not completely removed, and some type of intercoat is used, theres a good chance what ever is applied over it will lift the substrates.

Thanks Charlie. So do you think the heat/shock creates the checking due to sub par materials or misapplication. And are there clears that are impervious to these circumstances? If this were my boat, I would want it fixed properly for sure.

Had a very similar issue on the back of my boat...now have a similar situation on the front sponson. The said builder fixed the back a few winters ago and so far, so good. Its definitely an issue with the clear. I will be visiting the said builder again this winter. I don't think this is something that is 'new' to them, just FYI! I think these things happen when your boat is used and not a trailer queen. Those with only 10 hours in 2 years don't have issues.

PS - I do love my boat from the said builder.

I've never seen a clear crack because of a "shock" situation like your asking. If you truely think about it from a physics point of view, the shock from say 115-120 degrees to low 70's is marginal at best. Think about how many times you've washed your car or truck in the summer where the surface was so hot it would take your hide off. I'd put my money on sub par materials before mis application. Any of the good suppliers, BASF, PPG, Sherwin Williams, etc. make some fairly remarkable products(clear) as far as durability goes. My personal choice is Glasurit and Diamont. Any of the good clears are very expensive, and theres a reason for it. Good luck. Oh, and I'm no expert, just stayed at Holiday Inn Express last night.

I've more than doubled my hours since I bought it. She ain't no trailer queen thats for sho.

If this were my boat, I would just want to get it fixed right, once.

And I don't see my habits changing. 120 don't scare me, and the boat gets damn hot, and the water is damn cold.

And I do love my boat. Said boat that is

Thanks Charlie. Just seems so coincidental that said cracking is right at the cold water line and no where else.

That could also be caused by something in the water thats reacting with the surface. Or the mil thickness of the clear is not the proper depth.
