Application
Remove tinder, rust and other contaminations from surface in a suitable manner. You can use MR 79 Remover as precleaner for removal of oils or fats.
Apply MR Penetrant to the part to be tested either by spraying, brushing, flooding or dipping. Allow to penetrate for at least 5 minutes.
Remove excess MR Penetrant from surface using a clean lint-free cloth lightly moistened with MR 79 Remover.
Spray MR Developer (e.g. MR 70) from a distance of approx. 20 cm on the dry surface, achieving a thin, uniform layer. Depending on the used penetrant, surface defects will appear as red or fluorescent indications. Please note: If the developer layer is too thick tiny discontinuities will not appear through the developer.
