Started off today with the stiffeners...backriveting them is very straightforward (100G) I moved on to the drain and filler neck (50 G). Finished up with three ribs(100G for the ribs) another 40 G for the fillets). I really had intended to get further on the tank today but its so hot in the shop I couldn't go on...plus my hand are sweating so bad in side the gloves the look like white prunes when I tanek them out. When I did the left tank it was 40 degrees in the shop and this time it's at least 50 degree hotter. The sealant is a lot more manageable but it becomes unworkable in about 90 minutes in this heat.
