The nice thing is the investment is very small. As long as you already have a compressor.

Larry,
I do actually have a fairly decent one of those and even some of the spray paint equipment. Just have to overcome intimidation and lack of time to line up enough pieces to make the set up/clean up worthwhile. And then there is paint. I once spoke to someone at Krylon who said that they did NOT recommend thinning their paint to use with a sprayer. Don't you have to thin it to make it work?

Anyone who has used a sprayer, can you chime in on what high heat black paint you used?
 
I have firm intentions to give it a run this spring Jon. I have most of everything necessary. I just need to get the paint.

I do see where the Krylon High Heat Max says it should be brushed or rolled. Doesn't say you can't spray it though.

It depends on the formulation. Some is so thick it would look like bedliner more than paint. I.E., the Kubota paint I bought. There was no way that stuff was getting through a gun not thinned. I used thinner and even a little enamel hardener in the mix. Shot a couple test spots and went for broke.
 
 
I see this on the Rustoleum High Heat quart:

Brush Goods: Mix thoroughly to ensure any settled
pigment is re-dispersed. Thin material only if necessary
with mineral spirits. For brush or roller application, thin no
more than 5%. Do not thin with gasoline, lacquer thinner,
turpentine, etc. Apply with a good quality brush, nap roller,
or conventional spray gun. A second coat is not
recommended.

Larry, what are the guidelines on how much to thin a paint for use in a spray gun?

Honestly don't know. I usually start out, about 30% thinner (reducer), the test. I honestly fly blind. When you're dealing with quality automotive paints the people blending it will give you the proper formulation to use, based on temp and humidity when you're spraying and type of equipment
 
Ugggghhhhh. If I give it a shot this spring, there is going to be sooo many unknowns that any negative results could be due to a number of issues.
 
So when Krylon says not to thin at all, that poses a challenge. Maybe start with what Rustoleum says on their high heat as noted by @Bruce and just 5% thin assuming the sprayer doesn’t clog up?
 
RE: Krylon. I am not even sure the "Do not thin" suggestion is directed at those planning to use it in a spray gun. It might just be that they don't want people trying to thin it when brushing or rolling it on.

I noticed in all the Q&A questions regarding using it in a gun, they responded that it was intended to be brushed or rolled. I am thinking they just don't want to deal with supporting the use of it in spray guns since it more complicated and prone to problems.

It seems to me that MOST paints in cans are intended to be brushed or rolled, but it seems like most of them can still be used in a spray gun. I would love someone to try it before this spring and share their results, but if not, I am gonna give it a try.
 
It depends on the tip of a HVLP gun. I used to use a 2.2 tip for primers and a 1.4 for base and clear coats. Thick materials can be laid down nicely, it just depends on the amount/density of the solids. You can also defeat the thickness by upping the pressure and changing the fan and fluid adjustments.

I’ve never seen how thick the roll on paint is, but I doubt it’s any heavier than the primers and topcoats I’ve sprayed in my days.

The clean up of an HVLP gun sounds far more intimidating than it really is. Cleaning out my guns takes about 2 minutes with minimal effort.

Can you post a link of what you’re seeing? I would be up for helping get people set up to spray something more budget friendly.

The biggest enemy for anyone spraying anything is humidity in the air, and moisture in the air line.
