I know this has been talked about before, but I now have an issue and I am not sure what to do. I bought a partially built model V kit that was produced in 99. I have now completed the kit and am ready to fly. When putting fuel in it for the first time I noticed white kreem coming loose around the cap area where you put fuel in. The rest of the tank seems to be OK. After reading up about all the issues with the Kreem should I pull the wings and all back off and try and clean it out and reseal them or fly for a while and keep an eye on this. Basically are there some of you out there getting along OK with the old Kreem or is this just an absolute NO NO to fly with it? Thanks for any help.
