some pics in my album of when i replaced tanks. only the top fabric needs to be removed over the tank. my project was a little more labor intensive as i removed 6 gal tanks and installed 13 gal tanks. i had to open the wing a bay farther out from the end of the tank as the drag tubes had to be relocated . it may cost more for paint but its worth it to paint the entire wing. new whites and old whites don't match .besides sanding and blending sucks, the second wing i painted the whole wing .
