patching those holes in your door

I was wondering what the best way/ways to patch the factory holes in your doors is/are. I was thinking fiberglass? Anyone know of something better? I'm not looking to make a sealed enclosure I just want a solid surface to Dynamat. I also know that Dynamat makes Dynaplate which they say is for this purpose but I've never seen anyone use it so if you have let me know. Thanks

With 1/8" plexi glass and all purpose caulking like this: very easy and works great!!!-A vision without a plan is just a hallucination-

Use 20 or higher gauge sheet metal and rivet it onto the door.Jeff

Aren't these holes for service purposes primarily? Window regulator, door handle etc. Riveting sheet metal to the door seems a little too permanent to me, I like the plexi glass and caulk idea myself. Easier to remove in the event you needed to.

Just dynamat the whole door with a single sheet of dynamat. better yet use the glass AND dynamat. LOL. it'll be one heavy door!

Thanks for all the input. Now i'm gunna sound like a dick and not do any of them because i found some 1" thick blue insulation foam board in my garage. I would do the Plexiglas but I have no money right now and my doors have 4 of those service holes in them and two of them have not one flat point around them. so i figured this foam board is perfect because i can carve it with a knife and my dremel to fit those crazy holes then use caulk around it AND its insulation! Thanks a lot for the posts, they helped me brainstorm Anyone know something that works really well on that tar that held on the plastic weather barrier stuff?

You can just drill-out the rivets, remove cover, do repairs, re-fit cover, rivet. The plexiglass will be held on tight with the caulk and plexi is easy to brake if you try to pull it off or slide some tool behind it.

After having the foam in my driver door for a while it works great but I think I am going to fiberglass them so I can put lowes-a-mat on them...lol.
