I presume you meant before the curing decreased the viscosity Andy?Ī common example of this is pin holes on the corners of cabin tops and the edges of gunwales because gelcoat has to be applied a lot thicker than paint it tends to flow down and collect in pools and the extra depth of resin causes more heat to be generated, thus more bubbles form in these areas.Įven when gelcoat is sprayed on areas that are 'U' or 'V' shaped are sprayed from both sides to get coverage and some will flow to the bottom, as you say Andy any extra catalyst added will only make the problem worse. I really can't face sanding through all of them! I'd be grateful for anyone's thoughts on this - especially Oldsaltoz! I'm thinking of painting over a couple of them for a few inches in an unobtrusive area this year just to see if they show through the paint at the end of the year. The hull has never been painted and is 33 years old. The chip (only about 1/8" diameter) is right in the middle of three of these hairline cracks joining two pinholes and it has gone right through them and into fresh gelcoat again.Ĥ. In one place, there is a small chip missing out of the gelcoat on the rubbing strake. There are none at all under a small area which used to be covered by a stainless plate for some drying out legs.Ĥ. They are worse on the starboard side -which on our berth is the side facing the sun for most of the day.ģ. As I go down the topsides towards the counter under the stern, the gelcoat looks like it came out of the mould yesterday.Ģ. on any vertical or upward facing surfaces. They are mostly in areas that get a lot of sunlight. I think these might be ultra-violet damage for several reasons:ġ. In places, there are very fine cracks connecting them together. Again, these are all shallow and all of them are open. I do, however, have a big problem now with pinjoles well above the waterline. As they were only about 1.5" above the waterline, I just extended the epoxy that I used below the waterline to cover them and now paint a boot top line in that area. None of the blisters / pinjoles were more than about 0.5mm deep. Interestingly, I tried sanding a few out and the gelcoat seems to be quite thick - about 3mm in places. None of them were big enough to have any fluid in and most of them were open anyway. I had exactly the same thing - a small rash just above the water line. The best looking cure is a 2 pot polyurethane coating, that will last for many years. However it is also doubtful that any major damage will result in using her for another season and planning a proper fix when you lift out next.Īnything you apply as a temporary cover will have to be removed later, and if it gets into the voids it may be difficult to remove as part of the preparation for the long term fix, depending on what you use may do more harm than good, like applying a coat of polish that has a silicon base would make it almost impossible to treat later without some major chemical silicon remover. I doubt there is a quick fix that could be applied in the next 3 to 4 days that will last long. After almost 30 years of weathering and no doubt a polish or two, you may have worked your way to the voids. It is quite obvious that the Buyers Guide does not cover these topics.Pinholes in gelcoat can be formed if too much glass was applied with the chopper gun causing high temperatures, others are caused by poor application of the gelcoat to the mould, and again can be made too hot so small bubbles form. Basically there boats are built outside in an openair Jim! This is what I was looking for. CC is lagging behind, waiting and waitng till there NEW factory gets built. The fit and finish was ALOT better back then. Look at the front of a CC where the upper deck meets the hull.ĬC is a great boat. Basically the fit and finish has more attention to detail. See how the seat bases are thicker, see how the interior is sticthed. That is a BIG difference ! With all that said. A heavier boat needing more HP and torqur to push that heavy hullĪ MC is 60% hand laid bi-axle fiberglass with 40% resin It is going to be very tough not to have the apperance of bashing when facts are stated.Ī CCis 100% chopper gun 60% resin to 40% glass. You are paying for the EXTRA Warranty that CC offers. Is FORD and Chevy the same?Īpples to Apples the CC is even more expensive than than MC.
