Eastwood's Roll On Paint System (Primer)

Received Eastwood's September 2020 catalog and it seems they have a roll on paint/primer system Hmmmmm Anyone see this? Thoughts?
Brought back memories of my 2nd car in 1971 A 1961 fxxd 4 door wagon 6 cyl 3spd on column I bought for $150 bucks needed a clutch - painted that wagon forest green hi gloss (rustoleum?) with rollers even the rear side windows was a good 20 footer
