Re: fixing hairline cracks in gelcoat

Normally, the cracks are all the way in the glass and will require glass repair.

Normally, the only time you have cracks in the gelcoat is from when the boat was built and starts to show with in a year or so. This is caused when they sprayed the mold, to much gel was applied in a area. Remember, gelcoat is the very first thing done to a boat when being built. Normally you will see these cracks around areas like hatches or where bends are.

If the boat is older, you will probable will fixing a stress crack in the glass.

Still, it's not hard and something every boat owner should tackle.

I call bull on that. Yes, it is important, yes if you are a DIY boat owner you need to learn, but it is tedious and time consuming.

If you have to fix the glass, it is probably because you have to replace the core. If you have left a proper bevelled edge, you need to chip out the core from around that edge until you get to solid. Maybe it will just scoop out when it is completely rotted, like the instructions say, but if you caught it early, you will be chipping out wet core partially encased in epoxy. And everyone tells you you can get the end cut balsa anywhere, but it turns out that you probably need to order it online. As for that whole thing about lifting off the top skin to re-use, that will only work if your boat has already completely delaminated. I guess you could just wait until your boat falls apart, but I prefer not to.

And no one ever talks about what to do if the issues are right at the edge, such as with leaks from poorly bedded stanchions toe rails. All of the books, videos and instructions pretend like decks leak in the middle, where there isn't any hardware. So, in the end, you just have to make a choice of techniques and run with it.

Agreed. But the wax certainly does make a difference as well. As does any accelerant like Patch-Aid.

Soon as the 'tone evaporates, crack is invisible again. But blatantly obvious when wet.
Great trick. Will use it in future, thanks.

Re: fixing hairline cracks in gelcoat

Hi, I'm from MagicEzy and my intention is to provide you with information which may help you repair Hairline (stress) cracks in a quick and easy way.

MagicEzy Hairline Fix was purposely developed as a DIY repair solution for stress cracks in gelcoat and fiberglass.

Here are some before and after photos showing a repair of damage very similar to yours:

If you have any questions about MagicEzy, I'm more than happy to help?

Re: fixing hairline cracks in gelcoat

Simply stress cracks in the gel?
I scratch out/clean w acetone andfill with tinted Marine-Tex.
Buff out lightly w/acetone dampened wipe. to remove surface smear before setting. Done!

Two seasons on and still great. No chip out, further cracking or break-out.. All this in a stressed area where ya step down from cabin top to anti-skid on coaming.

HTH,
Paul

Product has been around for quite a while-no pics at all of any repairs after a few years?

Does the guarantee only cover replacing more product? What exactly are you guaranteeing, and what exactly will you provide in the case of a product failure?

Sad that the person promoting a product wants to see images from previous repairs from years ago, yet they lack the testing of this or do not want to show the fixes from tests they have done during development.

If it was my company or product that i was selling, this would be tested BEFORE the product is launched to the public. Seems like it would be a cheaper and more self selling product if i could show not just instant fix but a year or two later fix....
