The effectiveness of Perma-Blue varies significantly among users. While some find it effective for minor touch-ups, others report dissatisfaction, stating the finish is faint and inconsistent, particularly with different types of steel. Reviews reflect a divide between it working adequately and not meeting expectations.
Perma-Blue is praised for its simplicity and clear instructions, making it a feasible option for users looking to perform blueing at home. Many users highlight that the application process is straightforward, though the results may not always match their efforts.
Several reviewers mention the strong odor of the product, which detracts from their overall experience. Additionally, there are mixed feelings about how well the product blends with existing finishes, with some users reporting that it appears more gray than blue on polished surfaces.
Multiple reviews suggest that there are better alternatives available, such as Oxpho-Blue and Dicropan. Users often recommend these products over Perma-Blue due to their superior durability and finish quality, emphasizing a perceived lower grade associated with Perma-Blue.
Durability is a common concern, with users noting that the finish can rub off over time and may require multiple applications for a satisfactory result. This aspect makes it less desirable for those looking to achieve a long-lasting effect.
