How big? Fiberglass is the only option unless tiny.

If the body is plastic (which I doubt because of the age) you can use a two part plastic epoxy. If it's fiberglass then take Colt's advice.

On the 84...you talking about the front cowel/body (polypropolene) or the rear body (fiberglass)? Mater66, what do you think about "vette bond" for filling the holes in the fiberglass?

holes in front and rear body parts

rifter

So, who has the best solution for filling holes in plastic?

Coltf1991

I've got two small holes (about 3/8") that I'd like to fill in the front cowl of my G9. Would my best bet be the auto parts store for some kind of two part epoxy?

On the rear fiberglass portion you will probably have to either remove the body or at a minimum the tire to do the repair effectively. You might want to drill the holes one size bigger first to make sure the hole is clean. sand the underside with around 100 grit, clean it well then apply fiberglass mat coated with resin. On the top side you can just put some resin in what is left of the hole then sand smooth and primer.
On the plastic front sand the outside of each hole so it has a small indent around the hole no bigger than a quarter (and don't go to deep).do the same prep underneath with the exception of brushing or spraying on some adhesion promoter in the areas and instead of using the fiberglass I use the plastic 2 part sandable epoxy smoothed on and put a piece of duct tape over it to hold it all in place. Go back to the top side a little adhesion promoter and fill the indent with the epoxy, sand it smooth and spray adhesion promoter then prime and paint. I hope I didn't confuse everyone so let me know If you need more clarification and always these are just my opinions and what I do so other people will have their own techniques.

Also, if there are any cracks in the body or branching off from the holes, drill tiny holes at the end of the cracks to stop them from spreading.

But always start doing the body work/repairing from the back side of the body
