Re: 81 Glastron SX-190 Transom and Engine- PICS Galore Update 11-8
Where are your troubled areas? right where the transom meets the hull? I also had some gaps here but those were unavoidable due to the rough surface left by the PL. If your trouble is in this area I wouldn't worry about it. As for strength I can tell you that I am tabbing in my transom with one layer of CSM and one maybe two layers of 1708 and calling it done. One layer of csm and one layer of 1708 is already several OZ/ft more than the factory had by far.
Are you getting airbubles on flat areas? If so I am not sure what to say about that. Any flat surface I encountered I had no problems getting the air bubles out except where pieces of CSM overlapped.
One thing I do notice from you pictures, did you sand down the areas to be glassed on the stock glass? Your pictures don't look like you did, but that could just be te color of your hull. This morning I spent an extra hour going over everything else with the flapper disc on the grinder.
This is my understanding, and although I did have some airbubles on the transom I have non that I am worried about.
On the transom I did CSM first as this uses a lot of resin and provides a watertight seal. Also, the CSMis much more easy to conform to the curves of the transom to hull.
Then I put down some 1708, which I understand is 3/4oz mat on the transom side and 17oz woven on the outside. On top of the CSM the 1708 went down very well, but I only used this for tabbing.
Stock, my boat had only Woven tabs on the sides of the transom to about 2" in and nothing over the surface.
Also, I did not thin my resin at all of the transom as the curves were not very bad and it was easier to apply. Something about today with the stringers required the resin to flow more easily than when I did the transom.
Another thing, I am able to resue paint brushes by letting them soak then dry in acetone after I go through a 12oz batch of resin then switch to anotehr brush. So far I have only had to throw away two paint brushes, but they are cheap and this might not concern you.
