This all doesn't bother me *too* much, but one day i'll have to sell it so I would like to try to get rid of the obvious straight edges where it was masked, and blend it in best I can anyway - but I'm worried about doing it wrong and ending up sanding off the good paint on the non-rusted parts of the panel in an attempt to rub it in (whilst ending up with primer showing on the new part and it all looking rubbish).
Anyone got quick tips on it, or just a reassurance that this won't happen and the sanded-off paint will prevent any loss of original stuff?
I'll find the answer in time, but the word of someone on the board who's done it already is always more comforting.
Cheers
