[Shop-talk] Metal cleaner for paint prep

[Bob Spidell]

I ended up with WD-40 Degreaser; no rinsing required (the gate is in 
dirt). Funny thing, rattle-can paint is about as scarce as toilet paper 
for some reason; HomeDepot had been picked clean in spite of what their 
website claimed and Lowe's wasn't much better but I found enough to do 
the job (I hope). While I was looking at paint at both stores several 
groups of people came in and bought a bunch of cans; has everybody 
decided to re-paint everything while on 'lockdown?'
