I have a flow control lever, just was so surprised at the radical difference in flow rate that it caught me off guard

Well the part needed alittle repair. While I was pulling vacuum a thin wall in the mould broke and was pulling air from the underside. I used gum tape and fixed the issue. Still had some dry spots where very little resin was on the fiber. But I was able to mostly repair it, got a lot of compliments from folks at the car show so hopefully I can really do better when I redo all the parts. Gonna really take time on the moulds next go as well make sure the flange is larger so I have more wiggle room.

One question, can u mix different hardeners with different resins? I want to mix west systems 207 ultra clear hardener with dura-klears epoxy. The 207 has a longer pot life than the standard hardener for dura-klear. 

Thank you again with all the help so far you all have really advanced me miles ahead of where I would be had I just tried to google and read stuff and figure it out myself.

My previous post had a question about mixing different brand epoxy resins with different epoxy hardeners. Anyone know if you can mix one brand with another? I would assume if you can that its contingent upon what the makeup is of each. But how would I know what to look for?

While you technically COULD do it, you need to know what you are doing, you need to be able to look at the data sheet, find out what's in each resin/hardener, and then adjust the mix ratios to make it work. Not quite as simple as it sounds, given most manufacturers won't disclose the composition of their products because they are commercially sensitive. You also need to remember that these are very complex chemicals, and manufacturers have spent a lot of money on R&D to make them. 

If you fancy wasting a lot of resin, you could do some testing. Even if you find a mix that cures, you will have no idea what the properties of the cured resin are.
