I think I'm learning
something here. My understanding of printhrough is the mat or roving showing through the gel or paint
. I thought this occured at the time of manufacture, either it happens or does not.
So it seems that over time the mat or roving can begin to show through even if it didn't originally. It seems this suggests the layers of mat or roving can change position over time, moving closer to the surface? Seems odd.
One can prime and paint
, it looks good, and much later print through occurs?
I have fifteen year old flag blue Imron over light blue gel coat. Still looks good if not bristol, no printhrough. I prefer the dark hull
for aesthetic reasons enough to not worry about the issues mentioned. I dont think the boat is falling apart as a result, hope not.
