can soak into the wood

I would urge you to look at the youtube video with the title "Wings West | Glassing Techniques

These guys are pretty good at what they do ...... When glassing RC planes, weight gain is a big issue, and part of issue is the weight of the glue that goes on the glass cloth..... The video pretty much covers all areas... Thanks
