68 barracuda 383s "Driver Paint Resto"

Well I got some work done today. I started stripping the paint with a 5" paint stripping pad, but it started clogging up pretty fast and it seamed to heat the panel pretty good. So I switched to a 7" (slightly used) 36 grit disc on a low speed grinder, then I hit the panel with 120 grit on a DA . I am pretty confident the grinding marks will be filled by the epoxy and high build primer. On a side note I always suspected there was some filler on the driver side fender, and sure enough it must of been hit earlier on in life. There was quite a bit of filler (maybe 1/4" thick). It was pulled and filled. I hope I can reapply the filler how it was because it was a pretty good job. Any comments or advice will be appreciated thanks.

If you want to save time having to reapply filler, as your stripping and come across bodywork/filler leave it and hand block the filler areas with your longest hard block until the old paint is gone. Use the old paint as a guide coat. If the old filler is bubbling or cracking then you will need to dig it out
