you will need the following
1 litre of base coat (thats the colour)
1 litre of base coat reducer ( that is the technical name for thinners in 2pac) 1:1 is the ratio for basecoat , this will give you 2 litres of paint . Thats alot for wht you wanna do
1 litre of clear (thats heaps ) most clears will be needed to be thinned up to 30% to get them to flow properly , esspecialy seems how you are painting at home without sufficient air supply , the hardner for the clear if its 2:1 you will need 500ml
1 litre of primer filler is over kill , most run 4:1 so you will only need 100ml of hardner and add 10-15% reducer
if you are painting at home and not in a booth i would recommend a fast hardner as it will dry quicker giving you less **** in the paint
oh and you will need 1 litre of top coat reducer for the clear , primerfiller, and clean up ( you can get away with using GP thinners but it will affect the gloss slightly )
