Drilling hole in fiberglass

How do you mount something like a rock guard when the only thing to screw into is fiberglass? If I drill a hole in the fiberglass and bolt a bracket, what kind of drill bit? Or, is it better to use something like gorilla glue to glue a bracket to mount the rock guard?

Rivets will do the job nice. Just use large washers on them.

I wouldn't trust any type of glue or adhesive to hold something like that. As for drilling holes, any appropriately sized standard twist drill bit will make a hole in fiberglass. If you do, you want to be sure to seal the rivet, screw, or other fastener with a good grade of marine sealant. Just squeeze a dab right into the hole before you attach your fasteners.

A lot of people have an aversion to making new holes in their trailers, but if done right, they are fine. If you take a walk around your trailer I'm sure you'll see about a hundred holes already existing. Windows, doors, hatches, vents, drains, propane gas piping, gazillions of rivets, fans, air conditioning units, etc. If you're not worried about them, why worry about a few more holes...

I hadn't thought about the washers; good advice. Thanks

Great advice! I forgot about marine supplies, like the sealant, being appropriate for fixes. And, I hadn't even realized the windows were holes; my shame. Thanks!

You'll find packages of rivet washers next to the rivets.

Oh, thank you!! I'm new to all of this. Right now, my focus is on legalities, safety, and strength of all my additions. THEN, I might consider cosmetics.

In my opinion all additions and modifications should have the consideration of making them have a neat, tidy and attractive appearance. To do anything less is going to be bringing down the value of the value of the trailer as well as your self esteem boost that comes with doing excellent all around work.


In other words cosmetics are important and should not be last on the list of considerations, they are simply part of the whole package of making, modifying and fixing.

Use stainless steel to prevent rust stains.

Trouble is, cosmetics are what you see when done, and you can't change it afterward. Any project needs to be done carefully and thought through before starting. A little care goes a long way in making the final product pleasing.

It's so satisfying to upgrade the trailer and then go on a trip where you have time to enjoy it. I get a lot of pleasure out of much simpler things when camping.

Heres a link on Amazon to what they call exploding head rivets that spread out more than regular rivets. Not sure if they have differant colors. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 The rivet kit that can be ordered from Little House Customs also includes some of those "exploding head" type rivtets.

Driling in FG

If your trailer has the "rat fur" on the other side, the drill bit will catch on the threads and pull out a lot of thread, making an unsightly streak on the other side.

Once the bit is just about through, stick a wire through the small hole in the center. Go to the other side and use a rotating punch tool to cut a hole in the carpet where the wire is sticking through. Then finish drilling the hole from the inside.

Instead of using washers for backup, a small wood strip can work, if you have several screws in a row.
