HVLP question spraying water-based poly

Not to get all 'clarke' about this, but tire rubber is, in terms of hardness. very soft but very scratch resistant.

Hmm. I'll have to remember that the next time my wife scrubs a curb. {:-)

When she scrubs a curb hard enough to hit the wheel on it, see which takes more damage.

Ahhh my HF gun comes with a 1.4 tip... and as I am just now learning that may make it come out to thin though I'm not sure I understand the mechanics of it. So perhaps that is part of the problem...

- Do you know what model you have?

- What would I have to check to determine compatibility? (beyond thread diameter and pitch)

Well the regulator "seems" to work in that at least I can dial up different pressures... Were yours *totally* broken or just inaccurate? (i.e. did you have to check against a pressure gauge to determine whether or not it was working or could you just tell by the dial)

Ahhh well I have the stock 1.4 tip so perhaps that is the problem...

I think you have diagnosed it spot on. I didn't (and still don't fully) understand how tip size works but you have pointed me in the right direction.

I think the problem is finding other than non-stock 1.4 tip sizes for this gun, though I have seen at least two alternative suggestions:

1. Buy a spare 1.4 tip and drill out the hole a little
2. Find a tip from other companies that fits...

Thanks for the pointers and experience!

OK - now that I am pretty convinced that I need more than my stock 1.4 tip, as a newbie and a hobbyist, what would be the most useful other tips to order assuming I might want to spray latex paint, lacquer, shellac, oil-based poly, primer (for wood)?

Specifically, before I start shelling out loads of money for all possible sizes what 1 or 2 additional tips would give me a good range of coverage assuming I already have the 1.4?

Thanks
