How to apply Molykote P 37
Clean the thread with solvent. Clean already used bolts with a wire brush. Spread an adequate amount of this product up to the root of the thread in order to obtain a good seal. For this purpose use the brush from the brush can, provided it has not been used previously for other purposes. Otherwise use a new brush.
