Gelcoat

Check at any of the local marinas and see who they recommend to the boat owners for gelcoat repairs.

There must be Corvette repair facilities in NorCal ? Marinas are a very good bet. Boats take a beating. 

This is possibly something you can do yourself - provided you plan to have the car repainted or are okay with a near color match. Each spider crack has to be traced and ground out with a small Dremel tip to the very end.  It can then be filled with marine colored epoxy if it is normal color (like red, black, white).  West Marine has a system that uses resin and a powder to fill such crevices too.

Here's article using the West products -

@WOLFGANG thanks. Mine hairline cracks and not deep chip. Was curious if the process is the same. It’s good to know all this so when talking to shop they don’t try to pull one on you 👍

Yes - spider cracks only go thru the non-flexible gel coat (usually).  You have to get to the fiberglass base for a permanent repair.  You can fill surface without grinding but it won't last long.

Often caused by like a baseball hitting the hood/fender or a stone thrown up in the wheel well.  The previous picture shows it on a boat where the hull flexes - so similar to near door hinges.  You have to remove the inflexible gel coat where it is cracked and fill it in with something strong that really bonds well (so don't use Bondo or sanding putty as they do neither). 

  Work like this is child's play for any marina that has fiberglass repair guys on staff. You'll never know there was a problem when they're through with the repair.

@slowshoes that’s my wish. Hope to find one and not experience a bad job before finding one 👍

Post  picture of issue you have.  If dark car rub on some white polish so we can see the spider webbing.  Mine is a black CMC gel coat and marine store have black gel coat repair kits so no color mixing required.  Gel coat can be sanded with fine (very fine for final) wet-dry sandpaper and buffed back to high gloss.

Had a black hulled 38' Sea Ray that had a little doc rash - two six inch scratches down to the glass. First repair estimate was $2500 not including haul out. Second estimate was more reasonable but still extraordinarily expensive. Generally, marine work is more expensive than auto repair so shop around (recently had a local marina charge me $100 for replacing two dead light bulbs!) Try to get a reference if you can as not all work is equal especially if color needs to be matched.

@WOLFGANG yes. HEre is the photo

Ouch, that's some high gloss!  I'd want to find where the stress is coming from and address that before doing the cosmetic fix.  Do you have stop straps to keep doors from flying open?  On CMCs the inner to the outer door panel is bonded together with what looks like std pink Bondo which doesn't offer strength. it could maybe be repaired with gorilla hair or kitty hair fiberglass mix from inside the door to relieve stress points.

@WOLFGANG yes it is very high gloss. SAS mentioned door slamming. Since the passenger does not have it he could be right. 

I think the doors are being allowed to open too far (to where the hinge is at end of travel which stresses the mounting points).  I'd shorten the strap 3/4" and reinforce doors from inside the panels.

@WOLFGANG many thanks. The doors don’t have strap but as you said probably good to have one. Do you have a picture that shows how they are mounted.

I like the use of 911/912 tie downs with a leather or sewn seat belt strap:

I did this exact thing to my car when I was doing the restoration. It just cushions the door from going all the way forward and stopping on the door frame to the cowl 

If you want chrome you can get the brackets from a Jeep parts house. I think they look better with the rest of the bright metal in the interior 

@Tab Tanner so the door will hit this piece and stop instead of leather strap?

No. The leather strap is just short enough to hold the door front hitting the body inside the door jamb at the front ( cowl area) 

Like this:

@Robert M thanks for the picture. 

The chromed metal anchors are called " Footman Loops " available on eBay.

Footman loops are  also available from West Marine.com in stainless steel.  I used two "peal and stick" foam pads about 2" diameter on each door. One on the door and one adjacent to it on the panel in the front door jamb area.  Works like a champ. No drilling and creating stress areas. Takes about 5 minutes to install. The foam pads never permanently crush because they only have pressure on them when the door is opened all the way............Bruce
