can i answer for NWH , i feel i know him that well, some is oxidised frames and you cant do there wfp, they leave spots, and they are good payers, and so jobs just dont merit wfp, like small ones, or flat roofs where you have to get ladders out etc etc
i think that's about right,
that's the reason why mine isnt all wfp, its a tool not the ultimatum, work is work and im not going to turn down a good job just because i insist on wfp, im not that rich sadly,
maybe you could give me some money?
