I am finish sanding my fiberglass top to window seam on my RV-10. In a few areas, to maintain a smooth finish to the top, I have sanded through the fiberglass cloth that covers the joint to the windows.
My question is, will this cause a crack long term after paint, or do you think it will be OK? Should I lay up a small layer of glass and re-fill? My worry is, I will then just sand back through that layer too to get a smooth transition. I suppose I could build it up back out further.
Thoughts?
Thanks

I was looking at mine the other day and I'm going to have to build it further out too. The windscreen it at least 1/8" proud and I'll bet it's more than that if I really measured it.
I'm planning on laying some glass across the gap to give the balloons some support when they go down.

That happened to me and I DID NOT go back and rework it. I have cracks around my windows. I was worried about that when I was building……..but now that I am flying (3 years) it does not bother me…….but that is me, I would just as soon were dirty blue jeans, old t-shirts, and not use a comb…..you may be different.

Two (one inch strip) layers of E-glass on a 45 bias around the windows and on fiberglass embedded blinds will prevent later show through, due to a few hundred hours of vibration

Yes, that is what I did. Then I sanded and filled to get a nice finish and I sanded through the glass in a few spots. Issue, or no issue?

One of the cardinal rules you don't want to break when building a composite airplane is that you compromise the integrity of the structure when you sand down and cut into and remove glass,,,, or even fracture the strands of the glass. Whether or not that will have any significant impact of the area in question on our -10's canopy, I don't think anyone here can answer unless they know the number of lay-ups, glass used, epoxy used, testing done,,,on and on. I installed my windows last week (flox,,,,,,no Weld-On for me) and will fair them in as best as possible with BID glass, flox, and micro. They may not sit perfectly flush with the canopy but I will leave well enough alone.

My building partner was an old Glasair builder and those guys know their fiberglass. Here is what we did.
After installing the windows (silk flex) we routed out a ~3/4" wide channel with half being window and half fiberglass canopy. We then back filled with flox (I think), resin and several layers of fiberglass strips. Sanded. The results were a very nice transition with ALMOST no cracking. I say almost because there are a few trouble areas that need extra attention. It seems the most challenging areas for cracking are the outer most lower corners of the windscreen which makes sense once you give it some thought. The next most susceptible area for cracking are the lower forward most corner of the door windows. I suggest you give these areas the most attention when focusing on your "crack mitigation" regardless of the technique you choose.
Good luck,
Robin

No issue if it’s the extra glass; probably not an issue in any case. I used 1 inch e-glass tapes from Aircraft Spruce over the blinds.
