I finally made a gain today. I was away from the project for a couple of days, than got back to it and spent what seemed like forever sanding. Here is where I started, the fiberglass is all set up and ready to sand.
There are some spots where I didn’t get enough of the epoxy removed from the cloth. You can locate these spots easily because they are shiny.
I will sand these shiny spots right down to the cloth. I suppose you could just rough them up a little and let them go, but I’m afraid they may leave slight bumps because they are already thicker than everything else. I’ve never tried leaving them, so I don’t know for sure, but at this stage of the game I’m not willing to take the chance.
I know you’ve seen this before, but here it is all sanded and ready for more epoxy.
I guess that’s not really true, I have a lot of hand sanding to do. I got as far into the points as the sander will go.
Using just my fingers to get into this narrow spot, it took the better part of a day to get everything sanded down to where it needed to be. It’s odd how things can show up when you think a spot is done. I came across an air bubble in the point that I had not seen when we glassed the hull. It’s a fairly big spot too, but it hid well.
I actually found this spot with a chisel. There were a few big bumps right in the very point and I couldn’t get in there with my fingers so I knocked them off with a chisel. I pushed a little too hard, and when it went through the bump it stuck into the mix that fills the point. It’s a good thing this happened or it would have taken a lot of work to fix when I found later.
Here is a picture of some of the shiny spots after being sanded. You can see them, but you can’t feel them.
The good news is that after applying the next coat of epoxy you won’t be able to see those spots any more.
Now it’s ready for epoxy.
The main reason for the next coat of epoxy is to fill the weave of the cloth. It will take at least two coats. I got lucky on the outside and got it in two coats, but it usually takes three to be smooth enough to make me happy. My wife came out and gave me a hand. We applied this with rollers with foam pads.
I use a chip brush to get into the points.
When we finished I spent some time cleaning up, and checking for the bubbles.
I’m not sure where these bubbles come from after putting the cloth on, but they kept coming for about an hour and a half. Here it is all done and shiny again, but tomorrow I’ll ruin that with the sander like I always do.
As I said, it’s going to need one or two more coats to get the cloth filled. Tomorrow I plan on sanding it and applying another coat. Maybe I can put the cloth on the edge of the paddle also. If I do get this stuff done I will post it tomorrow afternoon. See you then.
