Title says it all, what should I use to bond it to the underside of the hood?

Solidlifters

Corvette panel strip adhesive by Fiberglass Evercoat is an excellent product. I think 880 is the part number in gallons for the NON SMC type fiberglass, but it's available in quarts also. It also makes an excellent filler for fiberglass. It's much harder than Bondo and supposedly the expansion coefficient is very similar to the PM type glass.

Fiberglass evercoat also manufacters a dual product for both SMC and PM glass, but I prefer the characteristics of the PM specific product.

I'm assuming you're going to remove the hood and turn it upside down. It will need to be supported level during bonding. With the added strength of the L88 box, if the hood is in a crooked position, it will likely have some fit issues when it's reinstalled, such as a rear corner slightly high. You will also need to rough up the two surfaces where the bonding will occur so the adhesive will stick, and of course since the hood may have been oily underneat it will need to be clean before sanding.

What kind of hood is it that you're putting the box under?

I went with Vanacor Corvette's AKA "Ecklers".

Vanacor builds all of Eckler's fibergtlass parts.

I used regular epoxy to bond it and then filled the crack with fiberglass resin. Maybe not the "correct" way, but it is on there very solidly!

I was informed, via a post on here some time ago, that a product known as 3M 5200 is the way to go when it comes to bonding body panels and the like. It is readily available at Home Depot and comes in the convenience of a caulk tube. I plan to use it to re-affix some body panel issues on mine.
Just a thought...

Cool, thanks for the info guys. :cheers:

5200 3M is an excellent product with extreme adhesive strength. When used on boats, which is what it was designed for, it is almost impossible to remove without their special solvent. There are a couple of differences in Corvettes, and the major reason I've been hesitant to experiment with new products. First of all, I've been using the 880 Fiberglass Evercoat product for over 25 years and have never had a failure with anything I used it for, so that makes it difficult to change. A chemical engineer told me way back then that the expansion co efficient of this product was as similar to that of the press moulded fiberglass as could be done outside of resin and mat, so as temperatures change there are less likely to be stress cracks and/or shrinkage. This same engineer stressed that common Bondo should never be used on a Corvette for the same reason, because the properties were different enough to cause problems. In years of fooling with them, I've seen countless problems when regular bondo type products were used. As far as the new stuff, including the 5200, I don't know about expansion/contraction/age shrinkage with any of these, and just haven't been willing to experiment away from the old stuff that I know works. The new mixing tube 3M stuff works well on the later stuff, but for now at least, I'm sticking with the old way on mine.

[Modified by Corey 68, 11:56 AM 1/15/2003][/QUOTE]I dont think they are the same.Ecklers makes their own glass.Vanacors a nice guy but his parts dont fit half of the time.Ecklers is higher in price but always fit better.I would also use epoxy ,just grind it good on both sides :seeya
