This is not Infused/Vacuum bagged, merely painted on. A base coat of resin is painted into the mold and allowed to go to tack, and then the fabric is layed and covered in more resin. I am just starting out playing with this stuff which is why I'm not infusing yet. (Although, I do have a pump and all of the consumables, so I may try it and see if that helps at all.)
Both the Mold and The part are sanded with 400-2000 wet/dry sand paper.
Silmar-249 resin used
Mold release wax and PVA paste used.
Not sure what is going on.
Thanks
