Help Needed: Fixing My Damaged Tub with Devcon Metal Patch & Fill

[NETSURFER802]

Hey everyone,

I have a pretty messed up tub that I need to fix, and I'm hoping to get some advice on how to do it. I've attached pictures of the damage and the Devcon Metal Patch & Fill (Charcoal Gray) that I plan to use for the repair.

Has anyone used this product before? If so, could you guide me through the process or share any tips for the best results? Any advice on surface preparation, application, and curing would be greatly appreciated!

Thanks in advance for your help!
