Rattle Can Painting (and use of strimmers etc)

[AMCrebel]

Whenever I rattle can anything I just press the nozzle and point the fucker at the car/van/bike. Watching Wheeler dealers recently I noticed Ed China continually pressing and releasing the spray button - how does that work?

And on an associated note - if I'm using the petrol strimmer, pruner etc, I start the fucker up, pull the throttle to max (or near) and get on with it- but I keep seeing(and more often hearing) people putting the revs on and off all the time like a kid with ped at some traffic lights.

What am I missing?

You let go of the aerosol spray at the end of each stroke as you slow down and will get a thicker build up if you didn't.

Rattle canning takes skillz.

I did the front arch of my last transit. Sanded it down, rust treated it, primed it, painted it and then laquered it. I made a great job and you really couldn't tell and it was metallic.
It lasted about four weeks and the rust started coming back through the paint in little blebs.
I fucked it off and bought the custom which is galvanised. We all know what happened next.

I really do wish I'd just kept it.
Even if I got it resprayed every year for the next ten years it would still have me cost less than that fucking custom.

You lived happily ever after?

That's exactly it.

Good, you deserve some good luck for a change.

By the way how's the holiday going?
