    Painting a frame with truck bed liner

    It's been suggested a few times before and I was wondering if anyone has tried it or seen it implemented.

    Winter here is like six months long and primarily characterized by the constant presence of salty slush. That means six months that I can't ride on my nice steel bike and will have to use the silly aluminum frame I pulled from the LBS trash instead.

    I was thinking that if a steel frame was coated with this truck liner stuff, then perhaps it would be sufficiently sealed that it's ok for riding through the chemical slurry. If so, that would be exceedingly cool.

    I've never seen it, but it'd be pretty sweet to do to a beater. It'll be ugly (not in a good way ugly), but ultra-practical.

    Try it out.

    It might look cool, and it would probably fend off scratches pretty well, but most frame rust happens from the inside out. Wash your rig once in a while, keep it framesavered, and just blast any scratches that go through the paint with clearcoat and you will be fine.

    Weird, I was just going to start this exact same thread.
    I want to have either an unpainted frame (like those NYC
    Bikes frames they're selling for cheap on eBay) or an old
    steel beater coated with Rhino Liner for use as a full-time
    winter bike.

    Rusting doesn't really have much to do with the strength or durability of the paint.
    Water and salt enter a frame through the bottom bracket, headset, water battle bosses (if you have them) etc... and that causes the rust.

    Years ago I sprayed my frame with fender well protector. Comes in a spray can and the stuff almost looks like the bedliner spray.

    So the inside is the real problem?

    I wonder if it would be possible to spraypaint the inside of the tubes with primer, or perhaps dip the entire frame into some kind of paint? I'm aware of framesaver but it seems like actual paint would be much more permanent.

    The orignal paint job my bike has now gets chipped or nicked almost every time I lock it up. It's pretty weak.

    This is a solution looking for a problem. Use framesaver, get on with life. You won't find too many people who used framesaver and still lost a frame to rust.

    years ago working in autobody i remember this spray on wax used on car parts prone to rust seems like if you sprayed the inside of your frame with this it would be allright.( i dont know what framesaver is if its the same thing ... nevermind.)
    or what about rust converter the primer that nuteralisaz rust and applys a ruberlike coating like pur 15 or somthing like that. has anyone tried this stuff on a bike ?

    If you decide to use the bedliner stuff, be sure to use gloves.

    A guy came into my office on Friday to pick up some stuff. When I went to shake his hand, it came over the counter where I could see it and I immediately jerked my hand away.

    He was wearing a suit, but it looked like I interrupted an auto mechanic. Apparently he had applied the stuff to his truck the previous Saturday! Be careful out there, kids!

    There really is no reason to put anything other than paint, or at most, powdercoat on the outside of a frame. I mean, do cars rust right through the paint? The issue, if there even is one, is all on the inside where the metal isn't protected. Deal with that, keep the bike halfway clean and wax it once in a while, and rust will be a non-issue. Even chips and scratches won't rust if you wax your bike. I mean, you wax your car, right?

    The paint is weak and scratches easily. Small scrape will quickly become a bloated bubbling festering peeling patch of rust due to the environment here. It's easy to find cars that originally had a small nick in their paint that quickly rusted and spread underneath the paint, and then caused the paint to fall off in sheets.

    Prior to deciding to go singlespeed on my commuter, I painted the chainstay with automotive underbody coating. Since the chain never gets close to the chainstay I don't know how durable it is. I painted the frame in June of this year and have had no problems with the paint. The bike is used five days a week for commuting and sits in the sun/rain all day. The paint consists of two coats of rusty metal primer (red), two coats of Rustoleum Hardhat industrial semi-gloss black, and one coat of 3M underbody coating on the chainstay. An added bonus is that black electrical tape matches the paint.

    I saw a Harley covered with that stuff once, my god was it ugly. Why do that to an innocent bicycle?

    Yes, and then I told him it was pointless, and then he started speculating about painting the inside (though not with bed liner), and I told him to quit worrying about the whole thing.

    Powdercoat+frame saver. Bar tape, innertube or truck bed liner or whatever on the area you bash with your nekkid chain lock.

    So you're both right--he has talked about both the outside and the inside of the frame.

    Cant you protect the inside by spraying WD-40 through the little pinholes in the various sections of the frame?

    Just have the frame hot-dip galvanized. The whole frame is immersed in an 850 degree Fahrenheit bath of molten zinc. The inside and the outside would be completely protected.
