Before I sold it, my Warbird was starting to see a lot of debris hitting the downtube. So while looking for my next gravel bike, I thought I would research protection for the downtube. I believe the Trek Checkpoint comes with integrated frame protection which seems like a good idea.

Was wondering if anybody is using frame protection (especially for the downtube). If so, what are you using? I don't think I would ever use fenders unless on a long tour - so fenders is not the answer I am looking for.

Thoughts?

I've heard people use "helicopter tape" but I never found a source or spec for it.  I'm interested in anyone else's opinion as well.

I use 3M Scotchgard Clear Bra Paint Protection Bulk Film Roll. Picked up a small roll for $20 and had plenty to apply all over my bike. I originally got it to guard against cable rub on the head tube, but ended up putting it on the seat tube, top tube, chain stays, and the insides of my fork. I don't use it on the down tube because I've got a bunch of externally routed cables there, making it impossible to apply. Works great and has protected my bike on many gravel rides the last few months.

Awesome, thanks!  Do you have a link to Amazon, eBay, etc, where you got it?  I'd like to narrow down the search since Google yields a ton of results.
Also with the externally routed cables - when it's time to replace cables/housing, that'd be the perfect time to add the tape to the downtube.  I've had a can of FrameSaver waiting to go on my winter bike, ready for whenever the BB or headset needs replacing.

This is the one I ordered from Amazon, but it's offered in several different sizes, depending on what you're trying to cover: http://a.co/0pS7sMX

You're the man!  Been looking for this stuff for awhile, but never wanted to pull the trigger on something that I wasn't 100% sure of.  Much appreciated.

Shelter Frame Protection, from Cantitoe Road is amazing stuff. I have it on my carbon frames and rocks are no match. It's 1.2 mm thick, specially formulated like memory foam and grips like crazy.

Con-Tact brand self-adhesive shelf liner, clear.  You can get lifetime supply for under $10.  It's easy to work with.  Barely noticeable.  Doesn't leave residue when you remove it.  Great at protecting paint finish from mud and smaller rock strikes.  I also use it where I install frame bags.  Don't use it on your helicopter (apparently there's a special product for that).

Here's a hint to make application MUCH easier.  I found it and references for tape sources at the below link.

Thoroughly mix 4 drops of liquid dishwashing detergent (not soap) in a pint (1/2 liter) solution of 25% isopropyl* alcohol and 75% water.
 Use a spray bottle to apply and the tape should be dry and ready to use in less than 24hrs.

A friend who owns a sign shop which does complete vehicle wraps uses that technique to apply vinyl "decals".  The vinyl is sufficiently porous that the water evaporates in a day.
