I've revisited this SLX and getting it ready for paint. The chrome is ok-ish enough that I want to keep it, but the paint or enamel is thick and really chipped. Any advice on media blasting? Would I be able to get it blasted without damaging the chrome? Any informed opinions welcome.

Always best to get it cleaned up by someone with extensive experience of similar cycle frames.
I've seen quite a few frames written off by an enthusiastic professional with little relevant experience.
In one case they still wanted t to be paid

Media? Walnut or soda - they should take the paint off without damaging the chrome plate or overheating the tubing.

Soda is what I had in mind. Yes I could ask a "specialist" but in my experience, unless you are going for new chrome, paint and graphics from them, they are not interested and make you out to be a cheapskate not forking out for the professional job. I'll be doing the paint and graphics myself and the chrome is good enough for a neo-classico which this frame will become.

Back in the 1980s the rather rare first series Colnago Mexico was built with Columbus Record tubing and often featured gilt plating. I write 'gilt' because I doubt that it was actual gold.

got be a missed pun there about repenting at leisure and guilt. Sorry, doesnt really add to the thread but had to be said.

my gut reaction is that walnut/pip-stone is the better option. I have vague concerns about soda/alkali causing long-term chem changes to steel and creating probs. A legacy of time spent in the nuclear industry.

There's probably a comment to be made about someone repenting at leisure and guilt, and who worked in the nuclear industry. I don't know what, and it also adds nothing to the thread, but thanks anyway
