<u>Step 8</u>: (continued)

Use your microballoons mixture to start filling in areas with sharp, compound curves; narrow, hard to get to areas; and to radius those corners.

Now it is time to beginfilling in thewing filletsof my P-39.

Notice I poured a thinner, runnier, batch of microballoons and resin for this application. I start to pour it in on a higher spot and let it slowly creep into the crevice and displace the air so that I get a nice SHARP finish quality line on my fillet when it is popped out of the mold. There is NO WAY I have figured out to get the cloth to accurately and completelyfill in such a tight space.

And "yes", that is an accidentaldrip of filler materialon the curvewherethefillet meets theside ofthe fuse. Notice in the second picture that the filler is spreading out and filling in the fillet. Also the drip has been wiped up so that the cloth will lay down nice and smooth. Again, had I not put a thinned layer of epoxy first,and let that start to cure out, I would have pulledup my PVA and ruined all the work up to this point;or, I'd have to leave the drip and likely have problems withgetting theupcoming layers of FG cloth to conform around it nicely and hurting thequality of the finished product.
