Started playing with the tip of the rudder today. Had to cut a groove in the forward face of the fiberglass to fit the front, had to sand down the back both for the notch and to have the right length of part.
After the drilling and dimpling and such.... i want to have a faired appearance and blend over the top of the pop rivets.
Reading all the fine posts and online information looks like I will scuff the part very well. Then mix a peanut butter consistency of flox/epoxy and seat the part in the top of the rudder putting this mix in the interface, then pop rivet to hold.
Then mix a little more and spread onto the joint on the outside using a tool to make it nice and even around the entire part.
After that sand it down, and then do a layer similar with micro balloons.
Then once I'm happy then two coats of plain epoxy to seal it all, with a 400grit sand of this to get the final effect.
Questions:
1. When in an application like this would cab-o-sil be used?
2. If pigment is used is it just in the final epoxy coats or in the previous coats as well? I suspect I don't really need pigment because I'll be painting later anyway.
