    Learning to paint with (compressor based) HVLP?

    I'm in the middle of a restoration. My only options for paint are Valspar spray can or enamel, I believe it's acrylic. I guess I could have a urethane mixed, which would be recommended for longevity, wet look after clear, fade resistance, etc from what I understand.

    Anyhow, I would like to give spraying it myself a shot. From what I've read, it's not all to terribly difficult, especially after some practice on cardboard.

    Then again, that's what I've read on the intarwebs. Does anyone have any personal exp. with shooting HVLP? Is it as easy to pick up with a little practice as I've been lead to believe?

    As far as paint goes, any personal recommendations as far as brands, etc go if I were to get a urethane mixed? I'm still a little lost when it comes to what hardner and clear coat get used with what top coat and what primer can be used.

    Any recommendations for a gun that isn't going to break the bank? I already have dryers on my compressor, both a refridgerated at the compressor and I usually use inline dessicant's at the tool.

    Thoughts?

    The biggest thing that will make or brake your paint job is prep-work. Any tiny scratch, blemish in the body work will be magnified by the paint.

    As far as the questions on harder etc. I suggest you go to your local, reputable, paint shop and ask them. They do what they do and get paid for a reason.

    A local paint shop could also recommend a good gun for cheap. Also they can give you pointers on painting technique.

    I knew I forgot something...

    Any recommendations for a paint shop in the south hills? I know of places like Masterwork Sternberger, but I don't think they handle automotive?

    I i where you id use something like OMNI = ..PPG actually makes it but ts like under $100 for a high solids clear and activator ...Just use all there products and be done ..Duponts cheap label is Nason they have a ok cheaper product also ..depends on what you wanna spend you could always go Glasurit which is some badass paint

    spray guns you get what you pay for and the cheaper the gun the harder it will be to paint ..if you had a place to spray it i could give you a few tips and let you use my Sata Jet Spray guns ..'

    your probably going to make a mess to be honest ..it will either be way dry and look like crap or way wet with some nice sags and maybe a good run or 2 ..you need to watch the wet edge and run a overlap thats steady and even
    vendors that did me right during my build .check them out

    I painted my car about 4 years ago, never painted anything at that level before. Got a H.F. hvlp gravity feed gun and used my 30 gal. craftsman compressor. I used the ppg omni base/clear, I am very happy with the quality of that stuff. There were 3 main things that happened to me which caused problems, all were caused by my lack of a place to paint. (basically in an open barn) Like said prep work is key, when I was doing the filler primer it was very humid and I think the primer absorbed water. Few years later there are a couple spots where the paint is bubbling. The other is dirt, painting outside sucks. The last is temperature, when I painted it was like 90 degrees. I put down the color coats nice and thin to avoid orange peel, but when it came to the clear it was drying almost as soon as it went on. I had to lay it down heavy to keep it from over spraying and orange peeling, which led to a couple sags. Since then I have painted other stuff with much better success, learned a lot painting the car.
