solder for code 100 track

Model Railroader Layouts and layout building

I was wondering if anyone had some input on which type of solder works best for filling small gaps on code 100 track. I realize there are different types of solder so is there one particular type that works better than another?

Thanks

Ross

Any electronics resin core solder should be OK. Never use plumbing acid flux.

60/40 alloy solder is best.
