When i bought my 69 I got two fenders to come with it. Both the fenders that were on it were shot. The two extra though needed some work but for the most part were in good condition. I had the rust cut out and replaced on the two. Now that i got it back. I started sanding it. I sanded all the old bondo off to put new in. Ok This part is weird. Around the parking light bezel there is a hole about a .25 of an inch in diameter. it loooks like a perfect drill bit there are 3 more that fall underneath it about 5 inches apart. theres no rust in them or around them and i sanded the backside of all the holes and theres no rust. It really looks like someone drilled 4 holes in the fender. Is there anyway of fixing this. there is no rust its just a perfect drill hole. Can fiberglass work to fill these and coat the backside of them with por 15. I need some ideas. I dont want to take the fender back to the guy.

It sounds like someone may have used one of the old style dent jerkers, "Slugger", to pull out a large dent in the past. You drilled a 1/8 hole in the center of the dent, then screwed the dent jerker, commonly called "slide-hammer" into the hole and jerked on it to pull the metal back "relatively" straight. Most body men then simply applied the bondo right over the holes. This made for a decent repair, but after several years moisture being absorbed on the backside of the hole thru the filler would eventually attack the metal and the repair would begin to fail. Simply applying paint over the hole and the squeezed thru filler on the backside of the repaired panel would have helped the repair to last much longer, possibly even the lifetime.

Nowadays there are better ways of straightening metal w/out having to drill the holes.

As far as repairing what you have. If you have access to a mig welder would be the best method. Simply mig the holes up and proceed w/ filler.

A more convenient method for the "do-it-yourselfer" would be to use a fiberglass reinforced filler, "Kitty-Hair" or "Everglass", over the holes then finish out the repair w/ conventional filler....again, remember to apply a coat of paint to the backside once the repair is done to keep the fillers from absorbing moisture. The 'glass reinforced fillers are "supposedly" waterproof, but they still contain "Talc" and it doesn't take a chemist to realize that the stuff absorbs water....use the paint on the backside as insurance.

I would prefer the 'glass reinforced fillers as opposed to straight fiberglass on bare metal for adhesion reasons.
