Cheers Richard & Paul. Richard the MGF ones are easy to take out with screws. I didnt want to knacker any of the paint by bodging them out. I think I'll take them out tonight, leave the car on the drive and have a bit of a mesh party in the front room when mrs and twins are asleep tonight and post the results later.
Just a question of do I use epoxy resin or mastic to stick the new mesh down?.. Good job on the pink stuff.
