No need to apologise. What you provided was fine too. |

I think the main problem is that the back panel is very thin, so if the lights get a nudge it suffers. It's a lot stiffer now because I've filled in the holes and laminated some more fibreglass on the back. I think the grey primer you can see is two-pack because it didn't come off with the stripper. I'm leaving it on except where I need to rub down the filler.
The car is 8407 which was BL dark racing green. It's going back to it's original colour. The nose panel was made by David Pounder and is off the same mould as the one on Howard Plant's car. |

The one I'm using, mainly because I can get it from the local car shop/hardware shop/chandler is Plastic Padding gelcoat filler. It's white as you can see in the pics and comes in two tubes (filler and hardner). The other one I've tried is from Scott-Bader aka Strand Fibreglass aka The Fibreglass Shop. Theirs is in a tin and is clear, but you can add pigment as required. The normal hardner is used. It's also a bit more liquid than PP so can be brushed into grooves.
There's another company called Fibretech that I've used for resin but I haven't tries their gelcoat filler. |

| Make sure that you get a good base for the filler before you put it on or it will split again. |

Well I had someone drive into the driver's side door in around 1981. Sometime later concentric oval cracks appeared covering most of the door, which I repaired. In some lights you can just see where the filler has shrunk slightly but the cracks have never opened up again. A few new ones have appeared around the handle and hinges.
Now I grind out the cracks with a diamond engraving bit (tungsten ones blunt too quickly) so the filler should make a good bond. The difficult bit is making sure that the filler goes right down to the bottom of the groove without trapping air. |

| Sorry Richard. My advice on preparation was meant for Craig. You've done far more gelcoat filling than I have! |
