What I'd like to with the rust converters is do they actually remove the rust or do they just seal over the top so you can paint over? Coz I've used a couple of converters which I found as useless as tits on a bull - they are only ever good for really light surface rust. Even light pitting it seems to struggle with. They barely scratch the surface and underneath the supposed "conditioned" layer it still harbours the rust in all it's glory. I'm not talking about thick rust with heaps of metal loss but even just light pitting - with maybe 0.5 - 1mm of metal thickness loss. Even when applied several times I still find I have to use a grinder anyway coz it check to see how far down the converter did its job and it barely scratches the surface. Underneath the deceiving top "converted" layers lies the rust untouched and going strongly.
I've only used Septone's converter (supercheap) and Repco's/Autobahn's KnH primer/converter which might be the reason why I having problems. How effective has everyone elses products been working? Have you actually checked underneath the converted areas to see if it's done its job or is that all it's supposed to do, create a seal over the rusting areas? Or have your converters actually worked and I've just been buying shit supercheap crap?
My bonnet is back from the strippers now (bare metal) so I need to do something bout it soon. Cheers, Eddie
