An then filled and painted, just need to leave for 10 hours and then go for a spin to fully cure it, and will see how long it lasts.

 Looking good sharpie. Just had a good old poke around underneath mine and it's still totally solid and the studs look rust free too   but I'm not taking any chances when I remove it. Just wondering whether there's anything I can do while it's off, to prevent it rusting from the inside, I thought of maybe cleaning it out a bit with brake cleaner then squirting a load of VHT paint down the end, (obviously with the silencer removed) and swilling it around in the hope that some of it might stick around the balance tubes and collector box area then pour out what's left. Opinions please. It's got to come off anyway, along with the radiator, cos I need to repaint the front of the engine and touch up the frame brace bars. Never endin' innit?

[fazersharp]

I worry that from what I have seen the paint flakes off, at least with the last two I have tried, so when it flakes off it is likely to get blown and clog your baffle perhaps.
I think the best thing you can do to protect the inside is to not do short journeys which lead to a build up of water vaper but a longer run burns it off   

[vinnyb]

Yeah maybe, I don't really do short journeys anyway. I rarely get the thing out unless I'm gonna be doing at least 50 miles, I live in a terraced house and have to take it down the passage so it's a bit of a chore so I tend not to bother unless I'm going for a proper ride. I didn't intend it to become a restoration project but it seems it has.

[fazersharp]

Right I can report that the Chem metal was sh1t - see 1st picture - completely blown/ fell off, so second picture re filled with gun gum.

Part of me thinks just to leave the holes and paint it and that way the water will drip out and prevent further rust. If I get a patch braided on then it will just rust under the patch without me seeing it

Would it be worth cutting that section out and having a plate welded on. The problem that when metal rusts to holes metal around it is already badly rusted and you'll be chasing it forever. sorry I don't want to sound like I'm trying to teach my grandmother to suck eggs.

Don't take any notice of Vinny his Granny is a professional eggsucker.
You have to be careful how you say that 

[vinnyb]

Not a professional, she only did it as a hobby but she was very very good.

 Hey Sharpie, Have you decided what you're going to do with your colander collector yet?

Not enough holes for a colander --maybe a pepper pot.
I am going with filling it with Gun gum as the picture, if I am taking it off to weld then a stainless steel one is going on instead.
