My shell was sand blasted before I bought it and wasn't protected and so has surface rust all over. What's the best way to deal with it, wire brush on the grinder and etch primer? Or do i need to treat with kurust or similar aswell?

Cheers

I would think about getting it soda blasted then a epoxy primer coating afterwards.

id get it media blasted or acid dipped. surface rust after sand blasting is a right arse to get out, as the rust it etched into the metal...  no wire brushing or chemicals will stop it from rusting.

That had crossed my mind, i did try a little with the wire wheel and like you say it didn't clean up as I'd expected. I've done quiet a few repairs already and got lots more to do should I get it done before I continue or wait till it's all done?

It will only get worse so get it done and epoxy primed. Then you can carry on working on it without it rusting in front of you.

i am in the same situation got a 1965 cooper shell and its been blasted and primerd it had slight surface rust in places when i had it but on the way home the heavens opened and the shell got soaked and now surface rust is appearing everywhere! need to get mine redone but not sure how much it costs tho.

yeah, unless you are going to be getting it dipped ( 2 grand procidure) which gets all rust everywhere, inside chanels and out, get it sorted now. 

 

 

what sort of thing you thinking? is it a big budget build?

[fife16v]

Glad I asked haha. Thanks for the help.

[fife16v]

Yeah I'm wondering about costs too, I don't have £2k to put into it for that I don't have a budget exactly just don't want to spend that much on dipping.

We can blast a mini shell for about £300-350, based in northampton ;)

[Artful Dodger]

it cost me 380 to have a whole shell blasted:)

 

look in my 1980 mini miglia build thread for the results:D

 

 

 

^^ get him to do it, be sure he will do a proper job.

That's not too painful unfortunately I live in Scotland so that might be a bit too far. I had look and there's a place about 20 mins from me. Anyone heard of them they've done a mini before from there website. http://blastcleansco....uk/systems.htm

I had my shell at 4 alloys blasted for £200 including collection and delivery. Mine was done about Sept last year and after working on the shell bare metal (welding ect) Im going to get it reblasted before I get it primered and into the body shop.

 

I would be worried about dipping a shell as residual solution stays in the cracks, over time on hot days etc it seems back out and damaged the paint from the inside.

A little bit of media in the box sections is easier to deal with (or at least it is for me seeing as I have chopped the shell about a fair amount)
