Great job CPU, and a first timer at that !
We never know what we can do until we try.
Question for all you glass gurus. I recently saw several cars that had this or similair mods done to the hood and 80% of them had some bubbling around the bonding edge area, once it hit the florida sun.
What causes this and can it be avoided by something done in the prep and bonding process ??

Thanks for the kudos. There were several points in this project when I wondered if I'd bitten off more than I can chew. I hope I stripped the scoop panel down low enough to get the best bond possible with the glass. Time will tell. If I find I didn't do this right and it bubbles or cracks then I can just grind it all down, redo it and then repaint the hood.
Your question is a good one. Maybe you might post it in the tech section. I'd be interested in reading the feedback. I don't think too many PFF readers are following this thread - may a hundred or so. Your post in the other section might get a better response.

You have to be careful with what you use to bond the scoop on with. If it doesn’t cure all of the way before you put your filler and paint on it will out gas when the sun heats it up and cause problems.

Cool! Thanks for the caution. I have not painted it yet - primer to come this weekend. I used standard filler - and will drill two holes in the underside spars - to make sure there is room for the air (and materials and gases) to expand and contract without trying to break out of the top. I did let the filler sit for a week or so before I did the fiberglass work - and didn't use as much filler as was implied in the pictures Archie sent me. There was a solid bond but I did have gaps on the left and right sides down near the lower part of the scoop funnel and the underside ribbing. Hope this makes sense to those reading this thread.

Did you just use fiberglass to bond it on? Or did you use some type of glue?
When I was in the Navy we didnt fiberglass anything if the temp was under 70 but that wasnt a big problem for our shop in Charlston SC.
There are sometimes issues where the glass wont cure all the way went its cold out and then can cause strinkage. But if you put it in the house and let it sit for a few days you should be ok. Put a heat lamp on it for a couple hours if youre worried about it.
Good luck.

The scoop was bonded (downside) with filler to the underside spars. The top and underside were then glassed. Kinda like a sandwich where the middle layer was the hood like swiss cheese (with big holes) and used penut butter to stick a slice of processed cheese to the swiss cheese - then used a sliced doughnut to sandwich the outer edge of the swiss and process cheese parts together. Man, I must be getting hungry!
Here is a crappy graphic to illustrate.
I let everthing cure in my apartment (in the bathroom with the door closed and the exhaust vent turned on) at a comfortable 78deg. The fiberglass had about a week to fully cure - so I should be fine.

How much is the Warber hood from Archie? I don't see it on his site. I must be blind.

Best to ask Archie.
I think it's $125 - but I haven't reveiced my bill yet. Archie shipped it to me before I paid - I have a good track record of paying him anyway and spent a ton of money on my car this past year with him. He might have given me a discount - so please don't quote me on the price.
Also I spent at least 40hrs on this project. It was my first. Archie's charge of $450 for a completed project looks like a deal. He does the work on a hood and takes yours as a core.
Ater I paid for shipping and the materials (resin, glass, bond filler, sand paper etc) his price seems like a deal.
I wanted to try my hand at some "honest" work - so decided to do this myself. This is really my first time doing glass and body work. I'm getting my car painted in a month and I'm sure the paint shop will add an hour to my paint job to cover off any time they might need to scuff the hood now that it isn't stock.
I've finisehd the scoop and the hood is back on the TAZ. Fixing the clearance of the rear trunk (over the TPI) and will post a bunch of picks late Monday or Tuesday!
Arch - the scoop looks great - very understated!!------------------
