Frequently asked questions
What is the difference between a converter and a remover?
A converter treats rust on approved sound metal in place. A remover such as Evapo-Rust uses a soak to remove rust from suitable parts.
Will a converter fix a hole or a weak frame?
A coating cannot restore missing metal or structural strength. Have holes, metal loss and safety-critical corrosion assessed.
Do all rust converters need the same topcoat?
Check the exact technical sheet and product label for compatible coatings, preparation and timing.
Can I soak a painted or plated part?
Check the remover instructions and the effect on the finish. Test only as the maker directs.
