Hi Guys. First post so please be gentle!!
Still fairly new to the tanker scene, and am in the process of modding my HL Tiger. I've done the usual: mantle, cupola etc, and also had a go at airbrushing for the very first time, but have a couple of what you'll almost certainly think are basic queries.

1/ Although I carried-out several coats of acrylic and finished with three coats of matt varnish, the paint is still rubbing away easily. Any advice please????
2/ The metal tools / accessories keep falling off. What glue do you guys use? I've tried cyano, but although it seems fast / strong....nope!!
3/ Disconnected the crazy red LED's from the headlights, modded the "covers" to form the slits, and tried a couple of very small bulbs that my father gave me (used on model railways) but they don't light up at all. Any ideas?? (I assume its a voltage / resistance / current thing)
4/ Would it be worthwhile stripping everything back off the tank, re-spraying the whole thing with plastic primer and starting the paint job all over again?

I don't want to go too deep as my pocket won't allow me the luxury, but I wanted it to be....well,..... mine!!

Thanks
