Default Cracked acrylic top can it be repaired?

I have the dark blue acrylic top on my c4. It has two cracks in the front. I know that Eckers want about $1200 for a new top. Has anyone had any luck repairing these guys. It seems to me if you used resin and color die you should be able to fill the cracks, sand it and then buff if out.

Anybody every repaired their t top?

Cyanoacrylate, and fiberglass powder, from sanding.

Get some wet or dry sandpaper (it doesn't break up into your powder), sand some fiberglass onto a clean surface, work it well into your carefully flared crack from the outside, apply the cyanoacrylate. Repeat for the interior, making sure to get the powder all the way into the crack, to meet the exterior-applied powder.

Buff and or clear coat. It can be done well enough to not be seen at all; it depends on purity of the powder, and saturation by the cyanoacrylate.


EDIT: cyanoacrylate is superglue.Similar compoundto your acrylic top.

I bought a reman top from a source that I will have to look up for my 86 for $500.00. Is your top see through? If so, you can't patch it. I don't know if a patch would hold very well considering the stress it is put through.
