To make a long story short:

clean/degrease inner fender>tape in fender as smooth as possible>use a mold release agent or pam cooking spray>lay fiber glass/resin (1-2 coats)>let dry>pry off> then sand/cut excess fiberglass and outer layer of mold and lay 2 more layers of fiberglass>let dry>sand smooth>bondo>sand>bondo>sand until perfect>clean>Prime (buildable primer)>block>clean>paint.

...and depending on what the fender shape is like you may have to leave some details out in order to get the mold off/out of the inner fender when dry. Then work them details/shapes back in afterwards. Its alot of work I will warn you..and messy...

so i glass the back side of the fender?

thanks

yes, the backside. Then build up from there otherwise if you do it from the outside the fender will be larger than factory. Also dont forget to mold the tabs/ears or mounting brackets to bolt the fender on.
