Hy guys. 

I have a bit of a problem. I was covering part with heavy carbon sleeve in 2 layers. Method was wet layup with vacuum baging. I calculated resin, covered everything with it and placed in vacuum. After curing carbon is in place and is fairly strong but it it seems that it got just semi saturated.

Is it possible to cover and dab resin into fabric or something else or piece is ready for recycle bin?

Main issue is that it is in 2 layers so I would like to be sure that under layer is saturated as well as upper one

What level of vacuum did you use?  Generally wet lay vacuum bagging, about 20% vacuum is a good starting point.  If you go too high, you will end up with a dry part as too much resin will get squeezed out.

Thanks for Your reply Warren. For my purpose I use your method from tutorial with house vacuum cleaner and packing bags so vacuum didn't exceeded 20% for sure. 

I checked one spare section I cut from a model and it seems that it might be good actually although not 100% sure.
To me it seems that if layup stayed dry, first layer is semi dry one and thats what bothers me because I am not sure how is that possible, especially with a lot of resin and vacuum. Anyhow I will try and use model, if it fails will inspecr further

Probably a good idea to post a picture, it feels like you are saying it is dry when what you might actually be experiencing is just voids and pinholes which are quite common in a wet-laid part regardless of resin content. If you can post a picture or two then we can tell you if it is actually dry or just high void content.
