Problem with primer on chassis

[Andy_B]

Thanks for all the replys...Ash G i spoke to the painter in work today and yes it is contamination i need to wash it down with sugar soap ...he also told me if i had spat on it it would have not come through !!! but think he may have been at the meths last night !! I dont have any spraying guns for my compressor and funds for the next few weeks running short due to TAX MOT on Family car so a brush on topcoat would be in order ...how much of that hard tank type paint would the chassis need ?
