I swear by the stuff and have used it a lot in clean ups and restorations. Can't help about the paintwork though, but I sure wouldn't want to risk any spillages. Perhaps run a test in a small spot on the underside of the belly pan.

I used it on this 2011 Fireblade. Headers had been painted black and had a lot of road crud on it when I purchased:

Is it safe to use on titanium systems?
It's not falling off, it's an upgrade opportunity.

It's very corrosive, if you leave it on too long it stains SS & strips chrome.... As seen on my SS sink & chrome taps !

As for use on Ti I suppose it would work but I would do a patch test somewhere you cant see it first...

Over use on SS headers will strip out the chromium...

The trick is, is to apply, agitate & rinse off with loads of water...
Making up since 2007, sometimes it's true...Honest...
