Thanks guys...unfortunatly, this was a plane I didnt build, sort of inherited it. The other 2 planes i built, I used a thinned out epoxy mix on the firewall and fuel area. Thanks for reminding me of the cornstarch, drew a complete blank on what powder to use. I've got a good amount in there now, and I'll keep reapplying and removing, should be good to go by saturday. Learned a valuable lesson...if your going to fly an old plane that has been sitting awhile, check the fuel tank!!!!
