I’ve always wiped on boiled linseed oil, but I have a project with lots of nooks and crannies and wondered if spraying very light applications would work? First, I wanted to make sure it would be suitable for spraying? Second, I wanted to know if I could get the coat light enough that I wouldn’t have to wipe off excess as that will be as hard as putting it on.

Thoughts?

Yes to both. Assuming you have a good spray setup, and can dial back the flow sufficiently you can do light dusting coats and build until you get the amount you want.

I see two issues though, one if you’re getting into nooks and crannies, then as you spray around and into those areas, you will likely get a thicker buildup that will require some wiping. I think it’s more realistic to expect to have to do a fair amount of wiping anyway. I do see spraying initially as a timesaver in uneven areas.

you have not said how big your project is or offered up any photos,
but, for me, I would skip the HVLP and break out the automotive touch-up gun ($13.00 @ HF)
for the detail work then when that is satisfactory, I would get the rest with the HVLP.
of course this depends on your shop setup and choice of application methods.
you may think it is “Old School” ~ but, that is just me.

You’ll still have to wipe.

Rich – I have had two HVLP sprayers in the past and for some reason,
I could not focus down to the fine detail spray that I needed for the intracate areas.
so I either used the air brush or automotive touch-up gun and the HVLP for larger areas.
(could it be my patience level ??).

Those guns typically have 0.5 to 0.8mm projector sets. Do you think that’s adequate for oil?

Edit: Never mind. It appears that gun has a 1.5mm nozzle (touch up?...lol). Nonetheless, I’ll stick with my Fuji Q4. It’s done the job for me for almost 20 years.

The project is a large model maybe 2’x3’. I’m not to the place to finish yet, but it’s coming in the next weeks. I think I’ll do some testing to see how light I can get it and how much wiping I need to do. Thanks for the advice. The project will hopefully be posted within a month. :)

My 4 state CapSpray is a touch up gun, depending on the tip I use. Even with a latex tip, it’ll get down to just above an airbrush.

As to getting build up in corners, I’ve never done a BLO finish I didn’t have to wipe down, since it’s impossible to guess how much oil the project will absorb, and any excess must be wiped off to avoid orange peel.

Have your say...
