there are 3 types of rust and ill tell u how to get rid of all 3.

1st is light surface rust which sounds like most of yours.

1st get some sand paper and it depends on the amount of rust as to which grade to use. i usually use anything between a 80 git for rougher to 600 grip for really light stuff. sand most of the flaky or loose rust off. then get the dust and crap off using a cloth or a air compressor. then apply rust converter and leave overnight. the rust should now all be coverted abck to metal. then what i do is use some rust kill spay paint and paint over the area to prevent it happening again.



2nd is rougher surface where its flaky or u might get a tiny hole, say u can poke a small finger through.

get a wire brush and brush away all the flaky stuff, u could also use 80 grit sandpaper to finish it up. then as above clean and apply rust converter. then if u need to fill in any small hole i like to use some "need it steel" stuff u can buy from bunnnigs from the paint/glue department. it come in a small tube and looks like blu tac. need it in your fingers and its soft like blu tac and then u apply it to the small rust hole u want to fill and in a couple hours it goes rock hard almost like steel. this is alot better and stronger than bog. then paint over with rust kill paint to prevent from happening again.



3rd is when there is a fairly big hole and u will have to weld a plate. basicalyl cut away all the rust until there is only metal and basically weld a plate over it. if u know how to weld u will knoiw what to do otherwise u will have to find someone to do it. then when its welded apply rust kill paint.


thats basically how to repair rust but once all that is done u can now also rust proof your car. erps is good if u have very small rust and its fixed or no rust and want to prevent it. i dont know much about it but i like to see under my car whats covered and whats starting to rust so i use the chemicall stuff.

get a underbody rustproofing from supercheap ans u can apply it everywhere under your car basically except exhaust and oiled/greased stuff. u can spray or paint brush it on. it will form a flexible thick sort of coating that will prevent the salt water toching your metal therfore stopping rust. i just put some all under my zook this week and u need to let it dry for 2 weeks, note u can still drive your car but not offroad.

and for your inside of your doors and stuff like that u use a wax based product in a spray can called tectyl 506 rust preventive. the reason u use this inside doors and alike is that if u use it underneath your car sand will stick to it because it will always stay tacky.


u will have to fix the rust yourself but if u want someone to rust proof it profesionally there is a small place that is really good in moorooka and they will spray under your car for $160 and it looks really neat. i did a test patch of their stuff after i bought the rust proof from supercheap and i like theirs better and its the same price for a 4L tin. their number is 38924992.
