I'd like to hear more about Skyloft from linclogs or anyone else using it. I did a google search and two people hated the stuff--said it took too many coats to fill, fuzzed when sanded, and sagged on humid days. But a couple people on RCU really liked it. I have some and I'm trying to decide whether to chance it on a plane. I'll try it on some scrap, but curious to hear what someone experienced with it thinks about the negative comments. Thanks in advance for any insight on this. Jim
