So what the best way to repair holes in the hoods?
I am removing the GMC logo, the POs locks and maybe hidden latches.
So some small holes but those lock holes are a good 1/2"
I'm thinking some aluminum disks with JB weld or something?

West systems epoxy. Use a ear plug soaked in the epoxy. Or sponge for bigger holes.

Kieth,
If you don't want to do it in two steps, (i.e. span with glass cloth and fill later) then use this cheap, sleezy and very effective plan:
Find a piece of something as a backer to put inside.
Cover it with something - old poly grocery bag will work. (I have expensive non-stick fabric I would use.)
Sand and clean the back side. And acetone wash is require because of the primitive SMC.
Mix epoxy and coat the all the inside surfaces including the hole edge.
Soak the tiny piece of glass cloth. (If you don't have, I can mail you some.)
Stick the cloth over the hole.
Put the block against it and secure it there with clamps or tape.
Fill the remaining epoxy with microlight or filleting blend to well thick of peanut butter.
Now fill in the hole.
If you don't have a cover block or tape of something and you rushed things a little, the filler might try to run out of the hole. You can block the door horizontal or cover it with another block like the one below.
The filled epoxy will sand or file much more easily the solid epoxy. West System stuff is much easier and more reliable than any of the polyester body fillers. It may be more expensive, but it is still cheaper than re-doing it because the polyester tripped too soon or not at all.
Matt - the offer was real.

I have bought West Systems stuff from Jamestown Distributors. For a long time I was intimidated and afraid to try it. I did buy the pumps (highly recommended). Once I finally got the courage up, I found the stuff quite easy to work with. They have lots of helpful how-to videos on their site.
Anyway, lately I noticed Jamestown has been heavily promoting their private label "TotalBoat" brand epoxy. Supposedly it is compatible with West Systems (as in you can mix/match Epoxies and hardeners). The TotalBoat stuff comes in plastic jugs instead of metal cans, has its own set of pumps available, but is significantly cheaper.
Has anyone tried the "TotalBoat"? I have enough of the West systems on hand now for several future minor repairs, so see no need to switch at this time.

Keith,
since you are a SMC expert take your coach up to my place, and you can help me patch up my coach as well. my rear marker light, and where my ladder mounts needs some repair. I patched a couple other holes on the side of my coach, and what a mess and pain that was for me!
Yes- Dale Ropp has to get the credit for the west systems epoxy repair using sponges and ear plugs. I have used that on a couple things, but ran out of the epoxy samples he was giving out, and have not quite spent the money on more. I need to, I could of used some epoxy yesterday as well on another project.

Jon,
I could do that, sounds like fun. Now we just have to find time lol
I think the end caps are plain old fiberglass right? That stuff is easier, SMC does require a different system due to the build in mold release, but it's still pretty easy. Yes it's messy and scary as you have to make a big mess to do it right. I use my 4" grinder and feather the repair for at least 2" on each side, thats a big hole, then fill with glass matt, the non woven stuff or you will see the weave through the repair. More important for a corvette than a GMC, but zero effort or cost difference. Fill the hole with fiberglass using bigger pieces as you fill. small pieces in the bottom, bigger at the top. I try to do it all in one shot for a better bond.
Let that cure, hit it with the 4" to take off any high stuff, then fill with a short strand filler. Sand and contour with 80 grit, then top it with your favorite bondo and then scratch filler.
I'm a fan of eastwood products for fiberglass myself if you want to do it right :D

There is no fiberglass on the gmc. It's either aluminum or smc unless
aftermarket parts have been added.

Like many of the boaters here, I've been using West System for around 30 yrs, usually keeping a couple of gallons on hand. I mess with some antique sailboats. But, if you need any quantity, it really hits the wallet. A few months ago, in some searches about dynel, I ran across several pro boatbuilders recommending Fasco, syaing they have used it long-term. I've just received a couple of gallons of various types, but haven't cracked the lids yet. Take a look at the pricing
http://fascoepoxies.com/
For my go-to material for small patches used to be Marine-Tex. But --and this very well might be just me-- I'm having problems with it setting up properly, so I'm switching to JBweld Marine to try that.
Tip: Save your old venetian blinds. The old blind slats make a great fairing batten.
Tip2: Rather than a sponge, go to a big box and buy a 3m pad for a commercial floor polisher and cut them up for matrix. Also makes for cheap 3m scrubbing pads, just whack off what you need.
Tip3: Instead of fiberglass tape fabric, get a roll of fiberglass mesh drywall tape. Use a couple of layers if you want a tighter weave. Bonus: It's slightly sticky on one side so you can lay it easily. Also, very thin, so you don't have too much buildup. AND, it doesn't fray much at all, so no loose threads around the edges.

Keith,
I'm going to have to work in here slowly. My cold has gotten bad enough that the exercise of using a keyboard is tiring.
First, with epoxy - No epoxy, not just West - Never Use non-woven mat. That is for poly and vinylester resins both of with have an acetone carrier for the catalyst. That mat is bonded with a material that is soluble in acetone. That material interferes with the epoxy bonding to the glass fibers.
Never buy fillers again. Use the epoxy and what ever fill material you want (West has a bunch). Filleting blend and Microlight are the two that do car stuff real well. Want it to level on a flat surface? Just mix it kind of thin and let it settle. Want to hang it upside down? Put on a very light coat of unfilled epoxy and then put filler in the mix until you can't stir it.
One important thing is to wash the surface of cured epoxy as it pushes out an amine blush that is a great release agent.
The only thing I haven't done successfully with the West stuff I keep on hand is spot and scratch fill. So, I buy a tube every other year. (Well, not any more as I don't do much of that these days.)

Paul,
Much as I expected, Gougeon knows about Total Boat. The response I got from my tech guy was that they have found not bond issues when used with West, but that the components are not compatible.
This is no particular surprise.

Ive had good luck with evercoat ( not eastwood ) SMC resin, and the Vette guys like it. Besides I have a bunch So I'll be using that.
Epoxy may be better, but id rather not buy more since my garage is pretty much full.

Since Evercoat is a polyester compound it does not bond well with SMC long term. There is an article in a past issue of GMCMI newsletters that I wrote several years back that explains why polyester resins don’t bond well with SMC. If anyone needs the link to the article let me know.
Epoxy is the only resin that will last long term.

After a little web research and a phone call to Evercoat it appears there
is only ONE epoxy based resin system that Evercoat makes. Its called
Everfix and available in quart and gallon kits. It is available at
Wallmart, Oreilly's and other retailers.

Sorry for the bunches of short posts but I am trying to work while also doing light research on this topic on the side. Most of the larger chemical companies marketing resin and repair products towards SMC repairs tout Polyester resin systems. Some of these systems are listed as "hybrid" systems. This includes Evercoat, 3M, and USC. I have used 3m 8115 which is a two part epoxy panel bonding adhesive extensively in larger repairs on The Pig. It worked well but this epoxy requires an expensive precision mixing application gun which could be cost prohibitive to many who wish to undertake these types of repairs in a limited frequency. Furthermore I found it challenging to dispense and saturate fiberglass matting with this product due to its thick viscosity. While the gravity defying benefits of the 8115 make it easy to keep in place compared to a thinner viscosity resin, the lack of wicking or saturation creates other issues such as longer application times and excessive build of the epoxy while attempting to mechanically force the product into the patch material fibers. I would love to read the technical info you have on smc and epoxy topic Emery as now I am quite curious.

You might want to check out the THE COMPOSITES STORE in Tehachacpi, CA. http://www.cstsales.com
They have small batch epoxies, carbon fiber, frp or pretty much anything else you need.
