To be completely honest....Fiberglass and old rust dont mix...just leads to lot bigger problems.If you have access to a welder the rest isnt gonna take to much time to resolve...they make a patch for that lip above the windshield and the rest is an easy peice to make from a small piece of sheetmetal...I know first hand what filling that spot on the roof with fiberglass does befause the ass jack before I owned it did it to mine....My drip rails are completely rusted away as well as part of the roof...Like said before if you aint gonna do it right...just leave it alone till you can,sell it to someone and buy something less rusty..classics are just that and its to nice to rig up for a quick profit to some poor dude who isnt suspecting it to be like that....Just my two cents
