I have a much loved Ciocc that I'd like to preserve. I have noticed some rust in my bottom bracket and the bottom of my seat post. I know about Weigle's frame preserver but I thought there might be a ramrod/brush combination made for some size shotgun that would work to clean up the seat tube before spraying in the coating. Has anyone done something like this? I was thinking a cleaning kit for a 12 guage might work.. If someone has done this can you guide me on the size of the brush? Likewise, if this is a bad idea I'd appreciate hearing about it.
Thanks in advance.
A 12 ga or 10 ga rod and bronze brush should work. If your tubes are too large for a good tight fit, wrap some fine steel wool around the brush until the fit is snug.
I've used the shotgun brush technique to clean various frame tubes and fork steerers. They work well.
Saw the bike in half. Clean thouroughly, then weld back together.
My bike's better than me!
Excellent! The simple, inelegant solution is quite often the best. Don't overthink it....

Ciocc. Nice bike. Is the bottom bracket cut out? if not, that may be whats causing the rust. Cutting out the bottom bracket ventilates the tubes in the frame and lets out water and condensation. I've always done it to my bikes by just drilling a couple of 1/4 in. holes in the bottom of the bottom bracket. Not very elegant but effective. If the paint is still in really great shape, take it to a frame builder to do a star or clover shaped cut-out. If you're good with a dremel tool, try it yourself.
I do have a cut out, but the only place I have to store it is unheated and the condensation is the problem I think. Now that you mention it I hang it upside down too so maybe I'll remove the seat and post before hanging it. I appreciate the help.

After spraying WD40 into my tubes, I decided to use a frame saver type product(called IronClad by Zep) so I had to find a way to get all the wd40 out of the tubes.. I did this using spray gumout carb cleaner and a portion of a sock fixed to the end of a 3 foot section of 12 gauge wire. I just twisted the end of the wire around the section of sock rag etc.. this worked pretty good and was a cheap readily available solution... I used two strands of wire and a bigger piece of sock rag for the bigger tubes, and a single strand and a smaller section of sock for the chain stays..
