Best way to smooth fender bolts?

demon34071 said
I have been kicking around an ultra clean / smooth under hood engine bay and the idea of not seeing the fender bolts keeps popping into my head.

I was thinking I can simply take the fender bolts, cut the heads off and weld the studs into the fender bolt locations and nut them from below.

My question and concern is welding the bolt studs into the thin layer of fender lip in a fashion that the metal will be strong enough and not tear when the stresses of bolting them to the car takes place.

Any thoughts?

How about carriage bolts. Nice round head on the top and nuts on the bottom?
Another thing you could use would be the bolts that look like carriage bolts that have an allen head in the center so you can tighten them down. Use some body filler to fill the heads before painting. That way you could remove the filler if you ever had to removed the fender again and it would still look stock on the underside.
