Evaporust is probably the safest rust remover out there- I've done 2 fuel tanks w/great results. It's also eco-friendly. just pour it down the drain when it's no longer effective.

On the subject of ceramic coating- make sure that they will blast & coat the system inside and out. Most better shops do so
and that often accounts for the higher price...

I had a pair of big block headers ceramic coated once (Jet Hot), with relatively little use and the car stored in a garage, not driven in winter, the coating has failed and is flaking off, holes rusted through. I had these coated when new  inside and out for longevity. They rusted out far quicker after coated when new than anything I've never coated or even painted and just drove year round even in salt and snow. I'll stick to rattle can high temp paint.
