This is why you have to feather the edges to have space to build up the plies and the form or whatever has to be the size of the "inside" of the section you are building up.
If you figured the wall setion was 3/16 then make it that much further inser and upu start by laying up a layer or so at a time.
You might have to lay up strips a couple of inches wide to get the shape to conform to the shape you wand.
If ypu screw up then grind it back off and start again

So I'm sanding it down after the weekend of rain and wind we had here and wondering if I should have a grinder with a hard wheel instead of my palm sander with 60grit paper?

I'm beginning to be concerned with my ability to deal with the multi layers and multi angles of this repair. I feel like grinding low enough to build back up will just grind through the top broken (separated) layers, I've attached a video to help explain what I'm worried about. How should I move forward?

I know what I would do about those big pieces that are basically sound but flopping around. Clean up the shredded edges on those pieces and the adjacent ones and then place some "basting stitches" along the edges of the big pieces and the adjacent one to it using some fine wire to hold them in the correct surface plane with the adjacent edges.

Got the grinder, got the flap disc, got it ground down, partially propped up (the 2 large flaps are screwed together) with towels in a plastic garbage bag underneath. Now trying to figure out what to do with these little flappy pieces right here in the front (the side of the the bus). They have no backing rigidity, but the form the angle of the side perfectly, all I want to keep them. Any suggestions on the backing for those little flaps? Piece of luan screwed on from underneath? Towels in a bag also (propped up underneath with some wood?

Hi Jonathan,
I know you have probably fixed your groomers bus, but I thought you might like an uneducated suggestion. I have never done FBG, but after reading D Whites thread I am ready to try. Have you considered using the opposite, and hopefully undamaged, corner of your bus to make a mold for the corner you need to repair? If you can, I would cover the undamaged section with something the mat and resin would not stick to, waxed paper maybe? Lay on your mat, soak and stipple it with resin. After it hardens, you should be able to flip it over (180 degrees) to match the damaged corner. Then trim your "mold", cut out the damaged glass section, prepare the mold to place three layers of mat and resin inside to form your new corner. After all that you will have a new corner piece, so you can taper the edges of the damaged area and your new corner, then just glass it in place.

I would love to see how your repair turned out, and to quote D White, Work Safe.
