Aluminium good variant small micro Filling cracks and narrows in metal. Since ancient times, this method has been used in the car factory 😎👍💯 Real good stop The only way to stop rust. Temporary solution. After years, it will be necessary to restore if metal rust will open somewhere in the future. Then again with aluminum tin fusible present.
Thank you for the comment! It was a trial for me, i spent $50 on product and used some of the stuff I had laying around. I was quoted $350 for a new tank to be made. so it was worth it for me to try! I’ve been using for a few months and it’s been great!
