I think it's no secret that I struggle with apray painting. Not one to take defeat lightly I have had another crack at it.
Problems I've had in the past:
Not enough room
Spraying too cold
Not getting the paint out of the gun - paint too thick
Not filtering the paint - bits of skin in the nozzle
So this time in preparation I bought a box of paint filters, some new primer, a litre of xylene thinners, a gallon of cheap thinners and got set up with a pair of infra-red heaters.
I took my HLV cabinet and tray off for grit blasting and etch primer. They did do the grit blasting but when I went to pick it up they hadn't primed it and and not wanting to lose the weekend I took it how it was, since I just bought a gallon of zinc phosphate primer. Set up my heaters to get the place warmed up and tented off an area of my workshop with polythene. I thinned the primer a bit and set the pot in the heated area to warm up. Tried to spray it and it was spitting so I thinned it some more and it went on pretty well. That was last night, this morning it looked like this.
No runs in it and only a few blemishes/blobs and some grit that was hiding in the seam of the rolled edge of the tray. I've nibbed it all off with purple scotchbrite, set up my heaters again and this morning sprayed it all with a litre of grey enamel. I had a bit of trouble getting the enamel to spray, needing more thinners than I expected but I think I got pretty good coverage. It's currently baking under the infra-red heaters I'll go out in an hour or so to see how it went. I know I got at least one good run in it but so long as I don't go out and find all the paint on the floor I think I'll be pretty satisfied. I have a pretty good feeling about it this time.
