Im looking into using silicone bags instead of the disposable nylon bags. mainly in order to deal with problems such as leaking bags, bridging, reducing consumables, as well as reducing the time it takes. Right now im still in school so doesn't have too much cash to throw around, I have therefore opted to go for brush on silicone bags. I have looked into using either Alan harpers starter kit or the ez brush silicone from smooth-on.

Mainly im looking inte you guys opinions regarding the subject as there is not alot of information out there apport from a few videos and articles but if feels like no-one is talking about it on forums and such.

what are you guys thoughts regarding:
brush vs sprayed silicone and brands.
distributing epoxy/resin. (all in one shot Alan Harper style, gravity fed/resin infusion or injecting with machine etc)
sealing profiles. (on flange, routed grove, wax strips etc)
flow distribution (morph runners, resin runners, Alan harpers REFLOW Flow Promoter, regular flowmesh, core or reinforcement with flow properties etc)
just wanted to mainly get the discussion started and your experiences and opinions regarding it all.

Are you making dozens of the same part, or are you doing one offs? I love reusable bags, but it is very much a production technique. The time and effort - and above all money - it takes to make a good, functional and reliable silicone vacuum bag, is well above what it takes to get a good leak free seal on a disposable vacuum bag.

The only real reason to use silicone vacuum bags is if you are making more than 10 of the same part, and then it will improve your production times. And realistically, you will waste some time and money in learning to make a good bag. 

Just food for thought in case you are thinking this might be the easier way to go for making one off components.
