Hello there,

In my opinion a really perfect finish could only be achieved with a properly degassed resin. During the infusion the resin in your part is under lower pressure, wich means the gas bubbles become bigger. Some of these bubbles than fuse, creating bigger bubbles, wich can be seen even after being brought back to normal pressure. Most of the bubbles leave the resin during the infusion, because of the lower viscosity of gas compared to resin. If you look closely, you might see very small bubbles running to the resin front during the infusion, while getting bigger. This extension is caused by the pressure difference. At the resin feed there ist allmost normal pressure, at the vacuum line there is allmost full vacuum. A properlyrics degassed resin does not degas at all during the infusion.
