Thread: Painting Tips Required.

I bought some spray putty. But also some Blade Putty.

Now that stuff is great fun to play with.

just remember, the more you put on the more you have to sand...

And the longer it takes to dry. Which is my current hold-up.

Plus my only can of colour buggered up. The seal under the nozzle is gapped and it's just hosing paint out the base. On the bright side, I've got the filler surround done in colour and it looks great.
I've used ~70g of paint from a full can.

Well that was exciting.

I vented the paint can with the buggered nozzle seal, then cut and drained it into a paint tin. All was well.

I sealed the paint tin and was carrying it to the garage when POP! Lid blew off with enough force that I dropped the tin and sent 3/4 of the recovered paint onto my shoes and the concrete.
Half an hour of water-blasting and degreaser action the concrete is looking presentable. I notice the lid on the can is again domed up with pressure.

I ease the side of the lid up with a screw-driver and am again met with enough pressure to potentially make a big mess. Press the centre of the lid concave, bang the sides down to seal and watch.
Bink!
In about 3 seconds it's built enough pressure to dome the lid again.

I don't know yet if it's the thinners in the paint gassing out or if it's the hydrocarbon gas used as propellant coming out of solution. Either way the tin is now sitting in the middle of the lawn with one side of the lid cracked open.

That is seriously annoying. It's 'instructive' to learn how much the paint inside an aerosol can 'store' gas, even when outside of the pressurised environment.
I found this out some years ago when I was trying to save some colour to put in an old nail varnish bottle for brush touching later. Shake that small tough bottle even days afterward, and it's contents come out in an awful hurry when the cap is removed.
Paint+face/eyes: Not a happy combination...

I won't know until I actually get the creases filled, but maybe 1.5mm required.

1.5mm needs proper bog ... You can buy small tins of plastic filler from supercheap if that's your only option. Keep away from the single part (non-hardener) spot putty .... that stuff is evil and shrinks like a bastard.

BTW: The dents probably won't be your problem, the high bit beside the dents will be

By Monday night it appears to have gassed out completely. That's ~48 hours.

I had paint splatters over my dust mask, glasses, face and even ears. Luckily it comes off pretty easily. The annoying part is I lost 3/4 of the recovered paint.

I did wonder about the single pot putty not being suitable. Shrinkage explains it nicely.

Is automotive filler different to builders filler and all the other types? I've been too busy with other stuff to look into it.
