Morning guys,

Please see my pics attached, imp having a problem withresidue being left in mould and making parts stick.

I believe it’s the spray mount I use to tack cloth in placeon the mould. I don’t use a lot but I’m thinking I won’t use any tack spray andlet the bag pull cloth into position.

Been using 3m re position able photo mount spray.

Does the epoxy resin react to this spray??

As sometimes resin has been left in the mould when I pulledparts out leaving me some porosity in the surface.

You've got to be using wayyyyy too much. When I use it, I can barely see it on the mould surface. I put the mould down on the ground and give the adhesive a very quick spray from a meter above it, let the mist settle down on it. Works like like a charm, doesn't leave any residue on the surface and epoxy has no problems with it.
