I used the black dye and sure wished that I hadn’t. It makes it VERY difficult to see the layers of the glass as you lay it up. It turned a simple layup job into a almost aborted job and a huge mess. I had even enlisted the help of a very experienced fiberglass plane builder for the layup of the windshield fairing, and we ended up with a heck of a lot more sanding after it setup due to the unevenness of the bids due to our inability to see the material as we worked it. He had never used it before and will never again, nor will I. The same thing could be accomplished by brushing on black paint or epoxy with the dye in it after all the sanding has been done. I know that I’m going to hear from others that they had no problem with it, yada yada, however be forewarned that it caused us much grief and with no benefit as we had to sand so much material off and build back more layers, that we still had to apply a darkening agent after the fact.

The issue is that you want the black layer to be up against the windshield. You can't paint that on later.   A compromise may be to ensure that the bottom layers are black. After that it should make much of a difference.
Like you forewarned, I was a fiberglass newbie and had absolutely no issues with this step. Perhaps I had better lighting along with my bifocals that allowed me to see better what I was working with? 😄. I suspect that there are more people that experienced none or minimal issues as opposed to those that did.

You shouldn't have to do that much sanding. Just add a small layer of micro as a top coat to smooth things out. If you are doing a lot of sanding, especially through layers, it's usually an indication of other issues.

I just used black paint on the inside of the windshield after I had roughened up the surface.  I used that paint line to tape off the outside where the top of the final layup went.  I haven't pulled off the plastic covering the windshield yet so I can't vouch for it's looks yet!

I used an assortment of PVC tubes with sandpaper attached .... used the 3M spray photo contact cement ..... but the best tool I've found for shaping fiberglass is a 1" thick X 4" Dia.  black wheel with 1/4" shaft that fits my angle die grinder.  Both the cement and wheel came from Home Depot.

I used left over carbon fiber from a Lancair 4 builder for the windshield.  I found the carbon fiber to be an excellent material for his application and it looks good on the inside of the cabin.  I have other places on the RV-10 project where carbon was a better choice than standard fiberglass.  One recommendation – you just cannot scuff up the glass too much where you put the layup.  This calls for the real course sandpaper.  Protect the rest of the glass or you get to buy a new windshield.

I’ve heard the issue of galvanic corrosion with aluminum against carbon fiber but offer that as a consideration when using aluminum into cured and milled carbon fiber joints, not when the fiber is encased in resin.
