What are they?

What causes them?

Where do they normally show?

Are they a serious problem?

Difficult to repair?

Do most fiberglass cars have them?

That depends.....

My Esprit has two or three very small cracks. It is a small price to pay for bodywork that doesn't rot and is immune from minor dents.

Look here....

**Pat found a thread which I wrote some stuff you may find useful.

What causes them?

****Its hard to tell without seeing them upclose it can be a number of things, poor lay-up of fibre glass, air bubbles, thin layer of gelcoat, body twist hard cornering that sort of thing perhaps.

Where do they normally show?

***I don't have alot of experience looking at other Esprits, but on mine I had small cracks on the wheel arches, the upper side panels by the petrol flaps, Some small crazing on the roof, this is a different story though and not stress cracks.

Are they a serious problem?

***They can be, depends on how far they go. Can also be just surface cracks too.

Difficult to repair?

***Most panel beaters that can work with glass should be able to repair these no problem. Its best to ask fellow lotus people close to home where a good place is to go with proven results.

Do most fiberglass cars have them?

***Am not sure, perhaps a head count here may help give you some numbers to start off with.

You'll see cracks in older Corvettes.

Plastic and fiberglass airplane wing tips will develop cracks. Since these surfaces are not structural, airplane mechanics will drill a small hole at the end of the crack to stop it from running.
