if you are after a good finish for cosmetics then hold back on the infusion and wait longer before infusing, make sure you have a 100% vacuum and then when you infuse give the resin time to degas, if you are worried about pot life then transfer the mixed resin to a pot with a larger surface area and wait till the resin is bubble free,
when you infuse slow it down a little with the inlet clamp and then once the part is wetted out give it extra resin, clamp off the vac side and then let the pot keep feeding and the part will be spot on.

se siete dopo una buona finitura per la cosmesi poi trattenere sul infusione e aspettare più a lungo prima di infondere, assicurarsi di avere un vuoto di 100% e poi quando si infondere dare il tempo di resina a Degas, se siete preoccupati per la vita pot poi trasferire la resina mista ad una pentola con una superficie più ampia e aspettare che la resina è bolla liberamente,
QUANDO SI infondere rallentare un po 'con il morsetto di ingresso e poi una volta Che la Parte E bagnato fuori dargli resina in piu,
fissare Il Lato VAC e poi lasciare Che la pentola a mantenere l'Alimentazione e la parte Sarà posto su
.

This is very interesting, so if i close the vac side and leave open the resin feed, the resin fill it up all the possible pinholes? Then i close the feed and leave the vac side close, is it right? (sorry but i'm very noob, i've started to work with infusion from some months
) Do you recommend me to heat some the resin or not before the infusion?

Are you wet laying or infusing? Either way, not enough resin and too much air are your problem.
