I'm building a Foamie with fiberglass/epoxy skin. I want that protective fiberglass coating wrapped around the opening to prevent water intrusion between the foamie layers if/when the window seal fails.
Did you cut your openings after applying the fiberglass?
If you cut them before, how much fiberglass thickness did you account for for the rough opening?
I know glass doesn't like hard corners, but with tape applied on the bias, a decorative trim ring around the windows to hide the broken strands, and maybe a small radius I think its doable to apply the glass into the opening after the shell is glassed...but what do I know. Just hoping to get some other opinions before moving on.
"SrMofo", a coupla points to ponder ...
i might suggest securing THE windows n doors you intend to install FIRST
next step is to determine what size holes after you decide on the weight of glass cloth you intend on using
YES a small 1/4 round over will be in your favor
cut and install the bias tape prior to glassing the sides so the edge of the side covering will be under your flanges so the tape feather edge will not be as much of an issue
i like to cut my bias tape a bit wider than factory tape and feather the edges just a bit more so they do not present you w/ a prominent edge
for my 2nd and 3rd coat of epoxy over the taped edge i mix a light epoxy slurry w/ wood flour to fill the weave and extend the epoxy a bit furthur out so any transition is not as much of an issue
ALL epoxy recoating is done as HOT COATS ... that is that once you begin you HAVE TO stay with the step until the weave is filled plus one coat of unthickened pox as a final coat
after an overnight curing and before the pox sets up hard and wearing a heavy leather glove i drag a piece of Sure-Form file along the edges to knock down any hard edge that may remain
then you will be ready to glass the sides right up to the window n door edges
BON CHANCE
