Rust to metal do i trust it?

im in the process of stripping my golf back to find the bad bits .
the real bad bits of rust need to be cut out and replaced but do i need to cut every bit of rust out?
Like round the windows where there is pitting where the rubbers were etc.
Can i just rust to metal them or will the rust just come back?

Be greatful for any info

i think its is only surface rust the get a fibre disc and get the paint & rust off with that then treat it with somthing then paint it

you need it sandblasted if you want to be 100% If its too deep, ie it goes through cut it out.

Its the only way to be sure

cheers thanks guys.

in my experience grinding rust back will either make the surface your working on go back to bare metal or will evolve into a hole...lol

If yer plannin keeping the car then i would cut out all pitted rust 8)

wel im going for it today getting rest of the car stripped back lets see how many other panels i need to add to my list lol

Got all the shell stripped back.
Any idears how i can sort out the rust in the roof gutters they have little rust holes all down them.??????

I echo other peoples comments so far

If it doesn't clean back to smooth shiny metal without removing much of the material thickness it wants chopping out.

Best way to tackle the rust to the rain gutters is first completly strip them back including underneath using paint stripper and a strip and clean disk . Then you can see what you're facing and how best to tackle it

had to do this on mine - but replaced a large section to be safe

hey mike its all stripped back
i take it u cant buy this bit how did you go about replacing it
any info would be great cheers mate.

if your going for it do the best you can, no reason to do it all over again in future then. and results will be so much more satisfying! im slowly tackling each rusty bit as i go along as im driving it on the road as im restoring...

Really depends how much rust there is and how confident you are with a grinder / welder.

If the rot is there on the out side it'll be worse on the inside

basically inner skin (attached to roof beams) wraps underneath up and around the roof skin holding it in place - along with 3 - 4 spot welds
+ all the spot welds at the screen apertures etc



idea is to cut the rain gutter through the outer wall only to allow you to remove the gutter as a staple - you can then remove the roof skin section leaving the lower bit of the gutter in place. need to heat the staple to loosen any seam sealer etc

you need to be really careful with the grinder as not to mess up the "staple" as this will need to go on in the exact position it came off - you can then replace the section using a doner roof  chopped from a scrapped car or repair the bit you have and refit it

in true haynes style refitting is the reversal of removal.

staple can be pinched over the skin and welded up along the original cut gap - weld will penetrate roof skin and tie it all up nicely - easy to dress back to

joint is then as it was from the factory



hope this helps

But as i said it really depends on how much and how bad it is - get some photo's up
