I have a 1974 el tigre with the fiberglass belly pan and its got some cracks and I wanna know a good easy way to fix the cracks
Sounds like an interesting product, but from what i seen on their web site, they still use a fiberglass mat on the repair anyway. Also they used the fiberglass mat on the outside of the hood, which is not the way to repair the hood.Spanky please take pics and document your process and progress, I will be needing to do the same to my 73 el tigre. I am curious if that product called POLLYALL 2000 would work on this, now that they're making it again. Has anyone tried it ?
Good advice. As said, if it's a crack in the glass, chase it to the end of the crack and grind it out, or it will reappear. The cracks in the gelcoat will reappear if you don't sand them all the way out. To do it right, you're going to need to repaint when the repairs are all made.If the cracks are only on the outside they are called spider cracks in the outer layer called the gelcoat. If you try to fill them without grinding a groove in them they will most likely reapear. The best way to fix them is to grind a small groove about 1/8" wide all along the crack and fill with body filler then sand and repaint. If you know of a body shop with experience on Corvetts ask them they are fiberglass bodied.
If the cracks are all the way through the fiberglass then you need to do some heavy sanding on the inside about 2 inches on both sides of the crack and use the fiberglass mat and resin to create a structural repair first and then move to the outside gelcoat repair as stated above.
Talk to your local auto body supply house they can guide you through the process.
None of this is difficult but it can be time consuming so take your time and don't rush it.
