Re: 1974 Ebbtide Restoration
Yes you did, and thanks to the fact that my Admiral works in a lab, I have been using them exclusively for years...
And Yep, that sounds about right...
I actually run into the situation where the amount of UV heat we get down here can and has kicked off batches of resin that I have mixed as low as 1/2% or .5ml to every 100ml...
I actually goofed once and mixed up a batch that I had only added
point one percent{.01**, and while it sat in the shaded area for over an hour it still hadn't kicked, that's when I realized my mistake...at the time it was time for some lunch, so I decided to do an experiment and pulled the boat out into direct sunlight...half an hour later, after lunch, it had fully kicked...
Keep in mind this happened to me when I was installing the "nailers" around the top edge of the hull, and it would have been no huge deal if I would have had to remove it and it really isn't a strength area, so I am not overly concerned with what detrimental effect the lack of catalyst is going to have in that area...up to this point, several months later, I have seen no ill effects from my brain fart...
Also, due to the temps we get down here, I rarely, if ever go above 1.5%, I usually stay in the .75-1.25% range...that comes from mixing many, many batches of resin over time...even in the marinas where I have done some work repairing fiberglass on some pretty big boats/yachts...from experience and through advice from the "old timers", this is the amount of catalyst generally used down here...
The only places I have heard they ever used more than 1.5% was during original production, inside of fairly cool warehouses where they could keep the temps in the 70's and in the shade...
On another note, one of the super gurus on the site, "oops!"...would go as high as 2.5-3% catalyst, in the frozen North when he was stretching his boat...
