However, no matter what i do, I still always seem to get some air trapped and it spoils the finish. Apart from vacuum infusion as that is another process that i have to learn and some of my moulds don’t lean to being used for that process. Any thoughts on the best process I can use to try and avoid this? And if it still happens, what is the best way of removing them and bringing them back to a good finished state once the piece is finished and out of the mould ? I have a large piece to do very soon so any help would be appreciated. Thanks in advance

This is a common issue when the bag is over stretched and can't reach the corners in order to to push the cloth into the mold, the bag bridges and cause resin pooling. Post a picture of your setup and it will be easier to help About bringing it to a good finished state, I think (not sure), that you would have to sand all the excess resin away, but then the finish of the pooled part would be different from the rest of the piece, so you would have to sand the whole part to make it uniform. Anyway, I'm new here, I'm sure someone else will come with further advice.
