So, the Marbocoat mould-sealer claims to leave the mould more shiny than if it was just ordinarily treated. Well, if you look at the pictures above, you can see that it actually does. Five coats of sealer and five coats of release agent and you can see the result.
I masked off the mould for about one inch (I know, thinking in old money – don’t care) around the perimeter so there wouldn’t be any issues with the tack-tape struggling for adhesion. As a comparison, masking tape applied to the treated surface just curls off.
The mould is treated, the templates are made. The modifications to an old compressor to make a vacuum chamber are nearly done (subject of another post soon), and the spray-booth is complete. The next post illustrates just how Dexter I’ve gone.
