Repairing big dents in a tank?

[MSTRS:Me]

Hmm. Dents are mostly out (using the welder pully outty thingy) but now I have to fix all the holes it made - feck it...

That is the downside of the weldwire/pull method. It works on auto body panels cos they are thicker (as a rule) & bog to finish is not an issue. Can't get away without weld-filling on a tank. Can possibly fill the tank with water to find the holes, mark, drain, flush well (for fumes as someone else said), then weld. Bog will be needed to finish, before priming etc

Yeah but it's better than 10 cm of bog.

John S is gunna TIG up the holes and I'll pressure test it again TIG, test etc. Lot of fagging about but at the end of the day - it's a cheap tank.

Shit, you should have seen this thing, it's like an elephant has sat on it.
