Right, guys, thanks for your input on this.
Given the advice here and elsewhere, I've gone away from the HVLP idea.
I've just ordered a decent compressor (from ebay, Kammo1) and it comes with, I'm assuming, a very cheap, basic spray gun that should be fine for running house paint through. To be honest, I could use a compressor in the workshop anyway, I've just never been able to justify it before.
So now that I have a compressor, what should I be looking for in a good quality spray gun? I'm afraid simply putting the word 'professional' in the name of the equipment is not enough for me. I've heard a couple of brand names thrown around, what brands would those of you in the know recommend and why? What features are desireable for shooting water-based sanding sealer and gloss coats? I would be shooting at least two guitars at a time - or 4 or 5 skateboards or a surfboard. Do I want a gravity feed guy or a syphon feed?
I know some of this stuff has been covered here before, so apologies to the forum police, but I was typing anyway, so I thought I'd get a couple of up to date thoughts on this.
If anyone sees a good deal on the UK ebay, please feel free to point me in that direction via this thread or pm.
Cheers
Buter
