It worked wonderful. I used it in the water bottle which they sell empty ones on here good value for the money. ### ⭐⭐⭐⭐⭐ rust conversion compound *by B***R on September 30, 2025* works very well, the directions must be adhered to ### ⭐⭐⭐⭐⭐ Great rust treatment *by D***N on December 6, 2022* I've been using this on my old Ford as I move through and repair the rust and it really works well. primer Adhesion after application is excellent. Yes, there is quite a bit of manual scrubbing if you really want to get into those hard to reach areas but well worth it in the end. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/9566181-3400-rustblast-1-quart](https://www.desertcart.jp/products/9566181-3400-rustblast-1-quart) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-18*
