I recovered a Dragon Lady 40 this winter that had bad oil soakink in the tail group.
I searched high and low for the K2r but to no avail! Then I did what any american would do, I improvised! I made a paste of naptha and corn starch, smeared it on and let it dry over night. I used a paint brush with the bristles trimmed down to about 3/4 of an inch to brush off the oil soaked corn starch. This worked great! Sometimes I did have to do up to 4 applications on the worse areas to remove the last remnants of oil. I also used heat on some of those last treatmenst, after the naptha had evaporate, just to bring out the deeper oil. I did use Balsarite on the leading and trailing edges to make sure I had a good contact with the Monokote glue. BTW never,never,never use cheep covering! You will regret it later, it takes the same amount of time to use good quality covering as it does to use cheepo covering.
