I thought I had my technique perfected and have been mostly happy with my results, but found a far superior (for me, anyway) method of getting a great wetout, one that worked MUCH better than anything I'd tried previously. I was doing the 8-BID layups (performed as 2- 4-BID ones) on the flap acutator bulkheads (and much prefer individual layups to multi-thickness ones done plastic-sandwich style, especially for something this thick) and found that a 4" length of plain old hardware store variety 1/4-20 threaded rod rolled back and forth over the layup with my fingertips gave me much greater control and probably the best layup I've done since I started my project. I wish I'd been doing this all along, the results are truly amazing. Try it, you'll like it.
