i also have just switched from Squadron Green to Bondo
. it has a finer grain than the green, has a longer working time out of the tube, sands and feathers better than the green and all round, to me anyway, a better putty
. one thing you have to watch out for, is after you open it a red liquid will come to the top. the advice i was given for this was to *knead* the putty with the top on the remix the liquid back into the putty.don't knead to hard or you will open a pinhole in the side of the tube (believe me i know
). also apply putty in thin layers as this putty is lacquer based. if put on too heavily it will deform the plastic.
