Products called Danish oil typically are a blend of some type of drying oil (such as boiled linseed or tung oil), varnish (or oil based polyurethane) and mineral spirits. The proportions vary and product names can be misleading, so one brand of "Danish" oil may be somewhat different from another brand. If the main ingredients are available, you can readily make your own with MS, BLO and any varnish you like, mixed in roughly equal proportions.
BLO is a drying oil. I know a lot of people like it as a stand alone finish, but I don't think it is ideally suited for that purpose. BLO will impart an amber tint to wood, which is attractive, especially when first applied. However, over time, it can begin to look dull. BLO can be reapplied periodically, to freshen up the appearance, but the affect will be temporary. Over time, the build up of many applications of BLO can result in a finish that remains tacky and attracts dust.
Again, I know many people use BLO by itself and like it. I think the ease of application is a primary reason for its popularity. I just want to point out the potential downsides of using BLO as a stand alone finish.
As for alternatives, consider shellac. A few folks on the forum have stated that they use it as a dipping finish. I've personally never tried that, but they claim good results. Shellac dries very quickly, so the process will be somewhat different than dipping in BLO or Danish oil. I spray my shellac and it's about as easy to apply as any finish out there. It dries very fast and is easy to clean up, with very little overspray to deal with.
If using a compressor and spray gun aren't feasible, Zinsser makes a shellac in a spray can. No idea if that is available in South Africa or not, but perhaps there is an alternative.
