Just starting to tape the seams with fiberglass and I am running into issues. In the first pic, you can see the raised edge running along the side of the tape closest to us. Do I just sand that edge down now that it is cured? Could I have done anything before to avoid this?

In the second pic, the tape job looks like a rookie (that's me) did it. Is there a way now to make it look better?

The solution to both is "sand it all down but don't sand it too far". Welcome to boat building!

BTW, take a look at my Lil Bit thread. Your stuff looks really good by comparison. you're doing a great job.

I am still learning myself, but it looks like your tape is the woven kind(more like cloth in my mind). The tape i got from BBC is much looser and held together with string. I used the tapes on the seams of my canoe and then put thin woven cloth over the entire thing and it was much harder to work with. The looser tape easily worked around corners and changes in shape for me, but the woven kept wrinkling and fighting any change in shape.

Honestly what you have there looks good to me, just sand it down and fill it up and sand again :P

Edit: You can see pictures of what I am talking about on page 14 of my thread.

Thanks to you both. How do I know when I have sanded enough?

When you see the glass pattern stop sanding. Otherwise you start cutting the glass. Once you get that far, assuming you are not putting more glass on the hull, use fairing compound to make her smooth as the prevebial bottom.

Been thinking... Will it be okay if I feather the edges of the fiberglass tape?

Yes. You should. My apologies for not stating that.

Feather the edges with a nice taper. Keep in mind that you need to be careful not to remove too Much of the tape though. It's a fine balancing act.

You will see some guys manage to lay tape and glass so week that it appears not edge feather is needed. There are two conditions at work:
1. They are using glass rollers and have a lot of practice.
2. They are not mere mortals.
The second condition plays heavily in that kind of glass work.

I had the same issue with woven tape on my little canoe. Just sand the raised edge off when the epoxy is hard.

You're working as neat as I think you can expect to get with that tape.

If/when I build something else, I will source biax tape; it is so much easier to conform to both internal and external corners and curves.
