Rollpan welding tips

[FresnoFleetside]

Hey guys, I just got started fitting and tack welding my rollpan on my '65 fleetside tonight.

I'm around stick welding a lot at work (I'm a union plumber/pipefitter) but as you can see from my pics, I'm still learning with my new harbor freight wire fed welder. (I know it's cheap, but it works for now)

I was just wondering if anybody had some tips on how to fill the larger gaps. (I fitted it up the best I could, and didn't grind much, but there is some large gaps, that couldnt be avoided)

I also need some help with how to use the bondo, or what else to use to smooth it out after I grind down my welds, before paint.

Thanks for reading, and I appreciate any help.

P.S. Don't worry, I have a real welder from work coming to supervise my welding as I finish welding it out tomorrow, lol.
