ive finally got around to doing the finish work on my rear fender..
if you remember, I got Dan Shady to help me turn a fender with a spare tire cutout into a reg fender...
I did some hammer and dolly work on it and got it very close ...I put a thin skim coat of filler on it and sanded it down ..followed that with finishing glaze...there were several spots that had bare metal showing and/or the filler was thin enough I could see the 1st coat of epoxy under the filler so I sprayed a coat of epoxy over the filler work
now the delima...when I was sanding, everything felt good and smooth to the touch...after I put the shiny epoxy on it you can see several flat spots..
since Ive got several different radius going on all at the same time..
what is the best way to get a good radius without leaving flat spots? ...once I sand the epoxy the shine will be gone and its extremely hard to see the flat spots...do I keep sanding and spraying epoxy (for the shine effect) or is there a simpler way to go about it..water maybe?
ive tried using just my hand with sandpaper but it doesn't help
the flat spots don't show up on the pics but they are there
after some youtubing I think Soft-Sanders may be the answer...ive got a set on order along with some guide coat powder
