Thanks @bobski Will keep this in mind... do I just damp the nhl undercoat with water or do I need to get a certain primer ordered?I apply it in one coat, still to the same thickness as 2 coats of multi though.
Trust it, it does goes OK (in one coat)
Never a polished finish though. Slightly grainy if anything.
Get used to the timings in small hits first.
Some batches have flash set on me, not sure if it was bad batching or poor storage from the suppliers. It was still salvageable though.
