Is there a product I buy or a certain way to fill the holes that the stock spoiler has on the truck. I want to take mine off but I don't want water leaking in.
Thanks for the help

 

Some people have gone to local hardware stores and purchased small rubber plugs that fit in the holes.

 

Although mine never sees the rain, I went the route Jim mentioned using some plugs from Ace Hardware and painted them using touch up paint. I am sure you could seal them with silicone.

 

What kind of truck?

Oh, you meant trunk.

Beyond a new trunk, or the plugs, you have to do metal work and have them filled, and repaint the trunk if you want them truly gone.

Or buy a different, more pleasing spoiler than what you removed.

 

Check the junk yards for spoilerless trunk and see if they would trade plus some cash.

 

^ this is a good idea

 

Try these, pre-painted "Bumper Plugs" in the spoiler holes if you're not confidant in your paint skills or just want it fixed in a hurry. Apply some clear silicone caulk under the head of the plug, insert into the 4 holes, wipe off excess and let dry. Also attached is a photo of unpainted black plugs. You can buy various sizes of these things at AutoZone, Pep Boys etc. I bought a couple packs of Dorman Panel Retainers for Chrysler, Ford #963-055 at AutoZone, but you can buy something similar at Lowes & Home Depot.

 

UPR Products have a couple of options for filling the holes:
