Well--ummm, it was 50 years ago at work [m/cycle shop] & we used to use [i think] Solpar Paint [spelling] Used to pour it on & broom it around, maybe push it around with a big rubber strip broom thingy like pushing the cow shit to one corner of the cow yard to scoop up. Damn good hard wearing paint it was. No doubt long gone now but something equivalent must be out there. Just googled it & no record of it & i thought google knew everything lol. Maybe i got the name wrong. Keeps coming up Solar but maybe the modern version.
