I have just had a british tank done that was in pretty poor condition and it looks ok
The tank will have to be absolutely perfect before coating ....... and not many are ..... every tiny flaw right down to the surface finish of the metal shows through
Powder coat makes a great base coat to paint onto though

Agreed you cannot powder coat over filler, because at the cure temperature of 150 plus it will degrade.
I had a similar problem, and went back to the old fashioned method of overcoming the problem.
Before modern filler was invented, one soldered the area wiped it, and afterwards rubbed it down as with modern filler.
I did just this to a lightly damaged area on the headstock of a frame, and powdercoated it. Perfect!
Purge the tank with argoshield and away you go.

Yes you can - but need to use the right filler.
I've coated over Lab Metal many times and have had great results with it.
See: http://www.alvinproducts.com/Products/Products.asp?id=1
There are two types - be sure to use the high temp version.

Very true. It can be wet sanded just as paint would be and then cleared over with a clear coat of paint for excellent results.

I've not had the problem of the powder not adhering to the filler. I suppose it might not stick to very large areas, but have had no issue with small areas of filler (around 2" square in size).
You can put clear lacquer over decals as most OEM tanks do. Multiple light coats. But you don't have to - just don't expect the decals to last very long
With decals being stuck onto fresh paint. Let the paint dry for
A few days before sticking them on.
Otherwise the paint gasses off under the stickers an bubbles them. DAMIK
An the lacquer. Use lots of very light coats before putting the final heavier coat on.

So lacquer over the top of the decals?
Personally I would but it's ultimately your decision.
If there not lacquered over. They will eventually peel an p••s you off when polishing.
Lacquered over will 'seal' them in place an make it look a lot more 'factory' then they will last.

I wouldent recomend that from trying that my self ! a big mistacke
Paintwork was cellulose ( crap to use compared to 2k)
With the vinyls applied a few days later. Then lacquered over with 1k lacquer.
No dramas an dead easy to keep clean.

I've painted over powder coat. IMO powder is the very best way to be sure all rust is stopped. Flat it down with fine wet/dry or scotch pads, then prime and paint as normal. I used a plastic primer.
