I finished all of the tank preparation on the left tank, deburring, dimpling, scuffing, cleaning, more cleaning with MEK, and set everything up to begin sealing all rivet penetrations and attachments with proseal.
The homemade balance worked okay but it is very awkward scooping the muck into cups on the long balance arms without spilling out.
I must have gone through 20+ gloves in mixing, frosting parts, forming fillets, coating rivet heads and so on. Lots of MEK to clean parts prior to using proseal and after to get it off of tools and anything that it comes close to... proseal will stick and string to everything!
proseal is fun... ha! mixing the two parts to a 10 to 1 ratio is quite a bugger with a home made balance... I need to retreive my digital scale.

|all contact points for proseal are scrubbed and cleaned vigorously|

|with proseal, every rivet is sealed and all contact points are carefully filleted smooth|
