I broke the golden rule on Sunday

Wouldn't it be wise to do that when the doors aren't fitted and you can paint them horizontal instead of vertical? Got mine on but still to transfer the window lock's. Now it looks patchwork so should I do a full respray....mmmm.

Not even near. I havnt even got the ruddy door tops on yet.
I have tried it out on a spare front valance and grill panel but there aint a lot of surface to get a good idea of finish and I have only undercoated them.
The spray I am using is a HVLP unit. Thats High volume low pressure and basically works off a vacuum cleaner motor in a small base station with a 2 inch hose delivering the air to the gun.
I have used one in the past for concrete colouring and like the idea. The problem however is the paint has to be thinned perfectly. They have a very rough spray pattern towards a traditional spray gun so the paint has to break and flatten as it hits the surface. Took a bit of playing with but I got there in the end. Not tried it on a vertical surface yet so more experimenting will be required.

Managed to get some of the semi gloss top coat on today.
First impression is, I wouldnt do a full gloss with it as the spray just isnt fine enough. Looks ok in the semi gloss though and after a second coat should be just the ticket. The paint I am using is new to me and looking at the data sheets its very similar to domestic gloss paint but with a finer medium and a polyurethane base.


Its easily thinned with white spirit and the primer is Wilco exterior undercoat. All in all a very inexpensive alternative to automotive primers.
The spray unit is one of these. A Chinese unbranded HVLP unit used for spray tan, fence defense and emulsioning walls.


All in all an alternative cheap system to brush painting with very acceptable results for a trattor but leave alone for top quality gloss finishes.

Would it work with automotive paint?

The above is an automotive paint, just one I have never used before. Pretty sure all coach enamels are pretty much the same formula as the one I used give or take a spoonful of oil. Its just that this manufacturer supplies mat, semi gloss or gloss in bronze green. As for cellulose you would have to give it a go. The problem would be drying time. The paint needs to relax a bit using this spray and I dont think fast drying paints would give you that. Owt suitable for brushing should be fine.
I actually painted the tricky bits on my door tops with a brush as I didnt think the spray would get in the corners but these bits are covered with the channels anyway.
