After a 3 or 4 goes with DeOx Gel we've got just about all the rust back to bare metal without damaging the surrounding paint.
One question may I ask - when you used Deox C Gel, did you apply it only on the rusty part or it didn't matter even it touched on the painted surface at all?
I used Deox C Gel on non painted parts before and it is amazing, but I never tried on painted steel.
Now I am thinking about using it on my rusty frame for touch up hence the question.
Yep thanks it's nearly a rider - just brakes to source.
I've done numerous car parts and several bikes now with Deox gel and none have had the paint affected by the gel. On some thinly painted suspension parts the surrounding paint flaked off but I'm not sure it was the Deox (as it didn't melt as such merely flaked off in strips as if it was not bonded).
Specialized appear to have the thinnest paint known to mankind (compared to MF and even Kona's) and the one above was completely unaffected by the Deox.
