Fiberglass hood repair/correction question
That corner isn't much, you could probably use duct tape to form your corner. When you grind it back, feather it, your probably going to get a fiberglass kit from the auto store. Get some 1 1/2" throw away brushes and plastic cocktail glasses and I use tongue depressors for mixing, grind the mixing edge square. Trouble is, the quantity you have to buy these. Make sure that you mix your resin well, this is a learning curve, how much catalyst you use depends on the temp, and it can get so hot that it will burn, watch where you put your mixing cup when done. When it starts to get off, your done, you may have to wait and start over, that's the learning curve. Wet the lay up area with resin. No more than 2 layers for side one, go out to the end of the feathered edge, make sure that your glass gets wet, but not soaked. Here's a trick, if you have your bondo. When the resin is curing, still tacky, but set. Smear a coat of bondo over your lay up, then you don't have to destroy the top layer of fiberglass for your first coat of bondo with sanding. After it cures, 24 hrs. remove whatever you have chosen for a mold. Grind that back similar to what you did yesterday. Wet that area with resin and probably one layer of glass. There is a trick to all of this, you are trying to bond this corner back onto the fender so that it it stays. Repeat, do the same thing you did yesterday. 24hrs. Sand or grind to finish, see how you did. You may or may not have to repeat parts of the process to achieve your goal.
There are other resins, cloth weights, cloth weaves , cloth for polyester, cloth for epoxy resins, fillers like flox and microballons . It can make your head spin. This is why I was hesitant to jump in here.
Oh, and fiberglass likes to be warm when curing. Not Hot, but warm, and it cures more over time , well past the 24 hr mark.
That curve at the back of the hood, is it warped that bad? Hinge adjust? Otherwise, that could get interesting for a beginner, even I would do some research with someone who knows more than me. Like a place that specializes in Corvettes.
