An oft-repeated question.
I have a Bajaj Pulsar 180 DTSi UG2, that is currently going an overhaul.
Right now sprucing up the fuel tank. It has developed two patches of corrosion, around 2-3 sq inch in the area where it rubs against the seat , and a pinhole in the bend near the petcock.
I have a few queries. Do note that I am limited with options, due to my location, unavailability of online ordering and apes who pass themselves off as mechanics here.
For surface rust
_______________
-I plan to wire brush and sand, the rusted patches and a little area around, down to shiny metal.
-Perform "tinning" over this new exposed area. This would involve applying flux and spreading molten 60:40 lead/tin solder over this area. And, subsequently sand the new tinned area with fine grit. This is just an idea and I am more keen on it, as this I might be able to do myself.
OR
I can go for pure lead brazing, by vendors who braze those old-world kerosene stoves and lanterns. I am a little tentative taking this path - no matter how much you tell them, the tank would come back with new nicks and scratches.
OR
Apply some corrosion proofing paint? Need ideas here.
For internal rust proofing
__________________________
-For rust removal, I plan to go the electrolysis path. I wish I could use Hydrochloric Acid, but that stuff is nasty - I am in so much awe of it.
-For rust proofing, I plan to use 2-part epoxy paint. The one readily available here is Apcolite 2-Pack Epoxy Finish ( only white color
). I know, from my research here and on other sites, that epoxy, allegedly, in a few years time, clogs up the carb. But, I am yet to come upon someone who actually faced this issue, except a gentleman who had a carb clogged due to an improperly done epoxy job.
OR
- Are there any other fuel tank sealing options, that doesn't cost an arm and leg?

These days I try to do a perfect job - both mechanically and aesthetically; earlier I was much nonchalant.
