I've been doing a bit of research on the net and came across this silicone rubber vacuum bagging and thought it looked quite good as it seems to do away with gum tape, bagging material and waste as it's reusable. Anyone used anything like it before?

Silicone bagging

I did, you can find some images and a video on my Facebookpage...

Like matt said that RVB (reusable vacuum bags) are a great option but are a little tricky to make there is a steep learning curve that can be challenging.  Also RVB in general react with epoxy resin so they are sometimes limited to less than 50 runs (prepreg is easier on the bags then RTM). At boeing silicone vacuum bags are used extensively for debulking the parts but then regular vacuum bags are used or even double bagged on high investment products for actually making parts (they do this due to vacuum seal quality of RVB but I don't think any of us are on that level).  I would love to hear from someone on here that was able to get a good seal and nice finish with RVB.  I have always wanted to try it as it would save a lot money on my prepreg parts but I haven't personally taken the plunge.     

Kind of forget of this post, here is an update with the video of the silicone re-usable bag that was uploaded last week. Still some improvements to be made but learned a lot out of this one!
