| How will epoxy bond to glass fibres with vaseline on
them?
| Wax is harder (when dry).than vaseline, so shouldn't
stick to the fibres, imo
We had the same concern. We took a piece of glass and put
a small amount of Vaseline on it and heated with a gun and
spread it out with a brown paper napkin. The heat makes it
spread like mad. The reason for the brown is that it
changes color to a darker brown when it gets greasy. When
the Vaseline was well spread, we then took another clean
napkin and wiped the area down while heating. This
absorbed any extra Vaseline, leaving a very, very thin
film.
When cooled we laid a new unfolded brown napkin on the
surface and put a weight on it and dragged it around, we
saw no Vaseline on the napkin. Unfolded brown is very thin
and changes color.
So we thought we would not need to worry about the
fiberglass.
Of course, with II, the fibers never touches the mold
anyway.
In my case I have only done this once. And I will be doing
it mostly weekly. I'll give updates.
