Hi guys, was browsing the net looking for some information on this and that. Came across the composites central forum and read a post regarding the EC video on perfect resin infusion and the ensuing discussion. 

Hi Matt

I totally agree with you.

The single most important thing I have learned from you is the turning off of the vacuum pump. Thats a scarey deal if you don't have your confidence up.Who would ever think of closing off the lines in the first place! It wouldn't have occurred to me. The first time I did and got no pinholes I became a believer. (of course the resin viscosity was the other part of the puzzle I had to overcome. Heating the mold and the resin first).

Yes for compaction and strength you want the pump running, but for cosmetic parts it is a totally different story.

Thanks Again!
