Print the images on thin Japanese paper (in order for it to be possible to run in a regular desk printer, you have to paste it on a printer paper - a thin string of adhesive around the edge). With a laser printer, the paper will then usually be used as is. With an inkjet printer, printing needs to be protected with a little fixative. Place the cut sticker directly on the wood and gently dab epoxy on a brush - carefully so that there is no crease in the thin paper. When the epoxy has hardened, you apply fiberglass as usual.
That makes sense to me.I have done it after saturation and under hardened fill coats otherwise glass is bonded to the paper and not to the wood. I think if you do it Bjorn's way, you might see the halo of the epoxy patch when you do the full glassing job.
Here is a dry run I did on some thin scrap plywood. It hasn't dried.I have done it after saturation and under hardened fill coats otherwise glass is bonded to the paper and not to the wood. I think if you do it Bjorn's way, you might see the halo of the epoxy patch when you do the full glassing job.
