Where do you buy Frame Saver?
Modern Bike seems to have the lowest price / shipping.
Not available on Amazon.

Thanks

IIRC, I bought mine at the LBS.

I will give that a try.

Thanks

...my local frame builder guy, Steve Rex, pointed me toward this stuff, which seems to do the same job, is available in spray cans for convenience, and is sold at Home Depot's across the USA.

So I found this thread that tested various products:

Frame Saver did not do well. Fluid Film and WD-40 Specialist Long-Term Corrosion Inhibitor came out on top.
Apparently Fluid Film smells really bad so I am not wanting to use it. I am little concerned about any of these products harming the paint.
Maybe I don't need to use anything as I read that steel frames really do not really rust from the inside, but water can possibly get in around the seat post if there are gaps.
I live in San Diego so the weather is pretty mild, no salt on the roads and I never ride in the rain.
Bike will be stored in the garage and I live a few miles from the ocean.
I had six different steel frame bikes back in the 1970 / 1980s and never had a problem with rust except on the outside of the frame.
I am wondering if Frame Saver is a solution to a non-problem?

I am definitely not an expert but if you have a bike torn down for maintenance or restoration there is no harm in using a rust inhibitor but, overall, I would call it a non-problem if the bike is stored in a garage in your locale/climate.

My 2 lira...

Boeshield T9 is another option, available in spray from woodworking shops (works great as a rust inhibitor on all those steel tools!) such as Woodcraft and Rockler, as well as bike shops or REI.

I've gone to FluidFilm because it's readily available at auto parts stores. IIRC it's less expensive than FrameSaver or Boeshield. I use it on my truck as well. I've never noticed a smell.

What do you guys recommend as far as prep beforehand?

I want to apply framesaver to a couple different frames but am concerned there may be rust spots/blooms in the frame where I can’t see.

Recently moved into a house maybe thirty yards from the waterfront...

Fluid film: I use it on my cars, works great where you are driving in salt 5 months per year. Smells like lanolin - which is what it is. If it's inside your frame I can't imagine you would ever smell it.
Boshield t9. Works very well also a good chain lube . no significant smell
frame saver. Have used it would rather use boshield as I have a gallon of it..... I'm set for life

There's no need to remove internal rust if you're going to treat the insides with some lotion or potion. What the lotions and potions do is create an oxygen barrier, which will stop any further rust.

Having said that, I'm in the camp that this is a solution looking for a problem. It is extremely rare to find a frame rusted so badly that it's damaged. One exception that you sometimes see are around brake cable guides, where sweat accumulates and through capillary action gets sucked into small gaps.

I have only done one frame, which came with some internal rust when I got it. I used ProGold since it was what was available, and thought it worked great. I would use again. After treating, it even “looks” much better inside 😀

When my daughter was in 8th grade she did a science fair project similar to the experiment referenced above on MTBR by jnbrown. She tested six or eight rust preventative products on large nails that were buried in moist garden soil for a couple months. I don't remember all of the products but I do remember that regular WD-40 was one of them. The hands down winner...by a lot... was Rig Universal which is a a firearms protectant. I'm not sure how you would get it inside a frame because it is the consistency of vaseline. I have started using it on my bikes stored in the basement at the beach in NH. The house is literally 100 feet from the salt marsh. The basement has a dehumidifier but I would notice a light powdery rust on exposed raw steel parts when we would arrive in late spring. Now I give all of those parts a light coating of RIG before I close up the house in the fall and it seems to have stopped it.

I use Boeshield T-9 as well. I think I picked it up on ebay. My two look at first places for such items are Amazon and eBay. Watch out for can size. Several ebay sellers are selling 4 ounce cans. Amazon has one seller for $13 for a 4 ounce can, and another seller for $18 for a 12 ounce can....
