Birchwood Presto Black BST4 Technologies - cold brush on blackener solution for iron and steel alloys traditional patina steel blue and black oxide touch-up (1 Quart)
The Birchwood Presto Black BST4 Technologies cold brush on blackener appears to have a mixed reception among customers, particularly when compared to other products in the Birchwood lineup. While some users express disappointment, citing that this product does not deliver the same depth of color or finish as the Birchwood PC9, others find it satisfactory for their specific needs. Notably, individuals who have used it in a machine shop setting report a positive overall experience, achieving an expedited black oxide finish on small parts without complaints from their clients. However, there are others who see little distinction between the performance of BST4 and competing products like Perma Blue, suggesting that price may be a key differentiator rather than effectiveness. This dichotomy in feedback indicates that while some professionals value the product for its convenience and satisfactory results, others looking for premium blackening options may find it lacking, leading to a general sense of indecision about its effectiveness relative to alternatives. **
