The lower forward 'wings' would be the area to check with a flash light for water & crud puddles which would promote rusting. Preferably with a near empty tank.
I had a crack develop between the rear mounting bracket and the base metal years ago. I used a NLA brand of tank sealant (Lubri-Tech SS Tank Sealant) to coat the interior. Due to the design of the KLR tank, one can't drain out the Excess sealant very well & apply 2 or 3 individual coatings. So I concentrated on 'layering' the excess sealant back & forth across the rear mounting bracket are.
Then I glued layers of inner tube strips on the frame spine pads to take ALL of the loading off of All 3 of the brackets! I highly recommend this to Everyone!
Still fluid tight.
Modify at "YOUR OWN RISK"!
