Any experienced body filler guys out there ?

That’s what I thought. Thanks guys. I realize there’s rust. I removed all paint, etc down to bare metal and there are a couple dime sized holes that need filled. I finished one spot and for my first time, I impressed myself, lol ! I mixed a portion roughly big as a fist. Added a drop of hardener large as a pea. Once it was mixed, hardened in 1 minute. I guess that’s too much, lol ! Like, no time to even apply it. Lol !
