I don't see you getting much attention here or on PN.

Thanks guys, I appreciate all the input! I thought my first concern should be matching what the boat was built with but the general consensus seems to be Epoxy for the underside, structural repairs... Clearly epoxy resin is far easier to obtain...

Epoxy will certainly stick to aluminum. If the shape doesn’t match that of the transom perfectly then it wouldn’t help much anyways. Lay it up in multiple thin layers (I’d use more cloth than mat) and gravity won’t fight you much. Keep revisiting the area as it cures and roll out any air bubbles that get introduced from droopage etc.

Epoxy is being suggested due to its strength and ease of working. It’ll stick to all other types of glass (though the inverse is not true). Availability for any of the types isn’t a concern unless you’re trying to source locally for some reason.

I was using Polyester resin on alum and it didn't stick so it made a great form... epoxy maybe not so much...

Yes, but the issue I have is handing a large sum of money to a shop that says "We can't guarantee that it won't crack again"... More than 1 place said this....

second layer on. 1st and 2nd layers tie everything together as it was before... Subsequent layers will bring the new stuff where the old stuff was removed out to the previous thickness... It's slow going, but it's going...

Laying all the layers at once is best, if possible. This will bond the layers better than if they dry and the next layer is mechanically bonded to the previous.

It worked!! I successfully put on multiple layers in one pass... Just took my time between layers enough that the previous one was tacky but not soaked,,, No sagging or dripping... Once the latest resin dries, I'll check the thickness compared to previous... I might be done on the underside...

Rick,
