I was wondering if anyone could give me any tips or point to a tutorial on how to properly widen fiberglass panels? I purchased pre-made body work from Equinox in the UK for my car but my frame is a bit wider than standard. The rear piece and scuttle need to be widened by 2" and my nose has to be opened up a whole 6".

I already split the rear piece to fit and riveted together with some aluminum strip for now-

Jack McCornack at Kinetic Vehicles has a couple of good write-ups about this subject:

to make a suitable filler piece for the middle of the back, first you must make a mold off to one side of the join, just a strip a bit wider than the gap by about 2" then centralize the newly made mold over the gap, then clamp/rivet it tight up to the surface of the panel and lay it up from underneath/inside, allow to cure and remove the mold, sand and finish to suit.

best done with epoxy not polyester resin if you can get it and chopped strand mat as woven mat will telegraph through to the surface.

good luck!

As always my post is gazillion years late...
You have already cut the panel.
Long straight repairs on fiberglass crack rather easily.
You may want to cut a weave on both sides in order to have a "multiple s" line.
Then make the mold as suggested and patch with some spacers to keep distance and alignment.
When I did my Catfish Nose extension, I did as you did, I cut a neat straight line which I later found out was not the best way to do it regardless of neatness.
Best regards.
Chanoquin.

Thanks for the replies. For some reason I didn't get any notifications and am just reading this now. Unfortunately I cut all my panels last week dead straight! Going to do my best now with the advice you all have given.

The practice that I use is to taper the both edges with a minimum of about a 6:1 ratio. 6 times as wide as the original glass is thick. If access is available from both sides, For small gap to fill, I will taper only 1/2 way thru the original panel, glass that, then grind 1/2 way thru from the other side and glass again. If extra thickness is acceptable on at least one side, overlap the original panel another 6 times the thickness. Remember, the resin is not where the strength comes from, it is the fiberglass. The resin is there to bond the repair to the original panel and the fibers to each other.
