dinitrol - aerosol or compressor?

[jools182]

I'm thinking about rustproofing my mx5

I'm just wondering whether to get the dinitrol kit for use with a compressor, or whether the aerosols will be good enough (and easier)

I have used aerosols on inner wings and easy to access bits but a compressor is better for injecting box sections as it has more pressure behind it. I think dinitrol comes in both aerosol and cans for an injection lance thingy(sorry can't remember the proper name) that works off the compressor. Remember to warm the cans in hot water too make the stuff as runny as possible and move any nearby vehicles as otherwise you might end up cleaning dinitrol of the paintwork.
