Sandblasting?
depends what you're doing it to and why. for example, if you want to paint some alloys wheels you really need to sandblast them first, if you dont the paint always ends up blistering when they get hot.
as for a pro job, well to be honest its very very easy. if you have a blastbench handy its really easy to use. i think of it as supersandpaper

Well buddy of mine is planing to sandblast his Mini,so since i`m going into rebuild myself (my 131),i thought of getting it done too.I`m planning to blast the entire body in order to remove all the paint,rust,etc.Might sound crazy,but i want this car to be in mint condition when it`s all done.
Doesn't sound crazy at all!
If you want to do a rebuild on a car you really want, whats crazy about wanting it to be the best that you can do?

Would not use sandblasting as its far to aggresive for panels. Use bead blasting where they use little fibre balls. Much more gentle, and will get the job done. Only get a Pro to do it though.

Nobody actually sandblasts in the UK, it's illegal, causes sillicoses. I have seen more than one car wrecked by someone getting a company who blasts heavy machinery to do it. It stress relieves the panels, they bend, dent and buckle and the car is scrap. You need a specialist. The correct blasting medium as well as the correct air pressure is vital. Do some research, get references from past customers, you do not want someone practicing on your shell.

Well,as you can see,i`m from Croatia and we still practice sand in our neck of the woods .The bottom line is i want to get the thing done what ever you want to call it.I must have the shell bared to the bone to get rockin`,but i don`t want some quack to mess around it.Will try to get some more info from past customers(swell idea! ).I`ll post some pics as i go along,but first i gotta disassemble and catalog all the parts.Thanks for your opinions,cheers!

There is the traditional classic car way too of using paint stripper to get back to bare metal. But gently blasting will reveal and weakness in the panels.
Andy.
That`s the general idea,if there is any weakness i want to find it.So if that means blowing half of the paneling off then so be it.If it goes,it means it`s no good in the first place.As said before this is a thorough rebuild.As for the paint stripper,it works just fine on flat surfaces but it`s the nooks and crannies i want to get.Well,it`s a nice day here so i think i`ll go work on the car a bit

Remember, some of the panels are very rare and difficult to get hold of. There are replica FRP panels available though. Bead blast is the way forward.

plenty of the turbobricks peeps in the US have blast cabinets in their garages just for cleaning calipers, turbo shells, manifolds, engine blocks, grimey stuff like that.
as for bodywork, its maybe a bit harsh, unless its a pro and they use absolutly the correct medium, otherwise they'll cut straight thru it

...otherwise they'll cut straight thru it
That`s exactly what i wanna avoid here
.I don`t have the luxury of another shell,so this has to come out right.I mean,the guy is a pro,he`s been doing stuff like that for a ages,so i think it should be fine.But to be on the safe side,i`ll give him a hood or something else that won`t be missed to see if this works.Hell,by now i`m starting to have my doubts:bang: .Theres a company near me (manchester rustproofing!) who blasts quite a lot of our wheels, but also has a booth that he blasts cars in, and all sorts of panels, theres loads of doors, boots etc all finished and on racks, from 1930's to modern, he first blasts them with what looks lice ceramic little balls and then primes them with a zinc type paint or enamel, or whatever you like, we also used a mobile guy a while back who blasted an old rs 2000 with a portable type machine, i was a bit unsure but he did a good job! i would like a little blasting cabinet, Ant!

Here's a link on eBay for you to check out in regard to sandblasting. It is an easy job if you are mechanically inclined, however, very easy to screw up if you don't pay attention to detail.
Good Luck!

Sandblasting is a technique which is used for cleaning rough surfaces using abrasive media.

Bit "off-topic" but the best method of stripping away crap on a bodyshell is acid dipping IMO. Shell has to be totally stripped of course but it does get into seems and box sections, takes filler out and exposes poor welds, this is the way to go for a serious strip and re-build.
Are those facilities available in Croatia?

it is also used for removing paint, and i would not call a painted surface 'rough'.
