I use Iwata LVLP , and GEO makes a toploader gun that only requires 6.6 psi at the gun to work ( if you do not have a compressor enough to handle a HVLP )

Yup, for sure!!!! I got the Iwata that you perscribed for me a couple years ago and I love it!!!! My DeVilbiss became my primer gun and my Sata, well, it just hangs there on the hook neglected!!!! Best gun I ever had, bar none. I'm certainly no pro painter, but the Iwata made me look like one!!!!!

As to what Bob said about the prep work, it's crucial to get it right and keep going over it till it is right... Acouple more times around the car block sanding is what separates the REAL paint jobs from the pretenders. Takes a lot of patience to get the blocking right when all you want to do is see the car with color on it, but it's definitely worth the extra time.....

I have these guns :

Gold Plated IWATA LPH-400 & Its good - good for pearls & kandies

Sharpe Titanium w/ 1.5 tip - Great for primer & lays down a wetcoat of clear might i add.....!!!

Finex 1.3 $85 cheapy - Works good for base coats

Sharpe mini w/ swivel cup(use for upside down) - Works real good

-- They all have thier own special place ...... No 1 gun can cover all areas

MAXED_OUT_RPM'S ----- Nevemind the HVLP business - its for those who need to conform to strict rules & regs ...If your in the garage painting - Just tune the gun to your liking....... Im alway tuning my guns while i paint - they are NEVER set at a specific point & left that way ......... Variations all come into play & adjustments are made accordingly..........

The best paintjobs are those with the most detail to the body work & prep before hand.... Paint is the easy part........

Start off with a lazer straight body & begin to shoot your paint..... your going to look for atomization & how well the paint is covering ..... Not too much / not too little........ keeping a good overlap & spray technique i good too......

Depending on temps wait 20 - 45 minutes between coats ....... picking out hairs & lightly sanding nibs with 800 inbetween can be done as well.........

Wait about a good hour or more depending on temps & reducers to provide the chemicals to evaporate....... Spray on your first coat of clear medium light ,,,,, Wait 20 minutes ,, follow up with a medium wet coat & allow 30+ minutes,,,, Another coat of Wet clear & more time to dry 45 minutes or so ( You will be able to check by touching a taped off area that gets alot of overspray on it , Such as windows ).......... Once Flashed off - you can do 1 more wet coat ............................................

Let car sit & dry for 15-24 hours depending on Temps/weather.......

Wetsand with 1500 to tackle the skin of clear..... You can SMELL the clear !!! Be Careful around any ridges - Stay AWAY !!!! Follow it all up again with 2000 & 2500 wetpaper & Buff that bad Boy out ..........

Here is the way I solved my what gun to buy process, started to look at brands that I had heard of, then read some of the hotrod bulletin boards post. After consuming large quantie's of information, meaning individuals post, manufacturers spec. and considering the pros and the cons of various brands, I next focused on my individual circumstances. They are 1 doing this as a hobby, 2 spraying at home, 3 knowing the value of good functional tools, 4 wanting a good looking/ lasting paint job... After that I ended up getting the Iwata 400lv , anyone knowing me knows Made in the USA is my first consideration of any product, so way a jap product? This gun seem to fit the bill , low press 16 psi and low volume 9.5 cfm , these numbers transformed into low over spray and low over spray then transforms into less MESS and good coverage, now I will not know for sure if this plan will come together cause as a home builder, spring will be the painting season for me and I will either think I am the man or just another dude confused and taken advantage of by the system............ let you know in the spring

Thanks chopsawbob, that is very helpfull. I guess when final sanding with the 1500, 2000, and 2500, Its just a quick even sanding to get any of the imperfections out of the clear so it turns out super smooth right?
When buffing, is it a polishing compound that i should be using? Is there a specific type that i should be looking for?

Thanks again

Very interesting information. I don't mean to sound negative but I am a little sceptical about advertising. I can understand production shop or custom painters useing the top of the line guns,but they are like any other hot item in advertising,they are over priced by 200%. The more of them that are bought,the higher the price goes! I would love to see a television special where a nationally known custom painter goes on-air and uses these 3 guns and then let the world see the difference! Call me sceptical,,,but in the hands of the artist/professional,I don't believe you could see a difference between the $100 gun and the $500 gun.
And shouldn't something be said about a beginner hobbiest(like myself),not having the skills to use the $500 gun,so start with a $75 one,learn the adjustments,pressure,mixing,technique and buy a better gun when you can 'effectively' use it? Over priceing makes my blood boil,,,,but,thats just my opinion

[QUOTE=FAYLUR] I would love to see a television special where a nationally known custom painter goes on-air and uses these 3 guns and then let the world see the difference!

Agree 100% that is exactly what I have been trying to catch on these car/motorcycle building shows. The one thing I keep seeing and it is mostly on the motorcycle shows is how little paint fog seems to be present in the booths as they spray and some do not seem to be using a booth. That is what made me hone in on the air pressures and cfm usage. By no means am I advertising the product, just representing a different prospective, considerations that were important to my purchase of a spray gun. That being said I will add this, higher priced tools (not the highest priced), such as the Hutchins and Ingersoll Ran do and have advantages that are very common. First they are repairable , not throw away, second the advantage to operate at different speeds with loads of torque makes the cutting,grinding usage of the tool just plain more efficient. This also helps the abrasives last longer and makes the price worthwhile. Getting what you pay for is harder and harder to get these days with all the me too products, cheep never means quality. Quality and cheep are two words that are found in the dictionary but do not have any truth when used in the same sentence of a sales pitch. I am not a tool collector (tool snob) with all the top brands, example my box,ratchets and wrenches are sears, but in the air tool world
HF and Northern tool have there place just not in my toolbox.

I like that....takes years for some to understand it!!

Your not understanding this correct... The gun isn't going to make the paint job better. Use the 75 dollar gun long enough and switch to that 400-500 dollar gun and you will see what the difference is. Easier to spray with, faster, more comfortable, etc. I've used a old caveman gun from 30 years ago that was cheap then and I've had things come out looking great but switch to that 400 dollar gun and it's much easier to use and less mess because of overspray, etc.
Not good to give out information unless you have USED BOTH the cheap gun and top dollar gun because you just wont understand.

YEAH BOY,I've never used a $500 gun and never will. I'll leave them for the guys that think they have to pay $500 to get a good paint job.

But when you do it for a living and blow color all day long every day the $500 gun will make you money I have sprayed with just about every gun , and they all lay the color and clear different , and finding one that lays it slick the first time is money well spent
True not all hobbyist's need an expensive gun , but it does help in the final finish , in time sanding and buffing The flatter you lay it the easier it is to cut and buff if needed .
Having confidence in your equipment also helps in knowing its not going to spit , pulsate , spray a bad pattern , ect.......
letting you concentrate on spraying !

Yup, a good $500 paint job is a laugher!!!!! Been many, many years since that was true. $500 won't even cover the materials......

How true Dave , my buddy spent $5100.00 bucks in material , all PPG .
I thought I was going to have call an EMS unit for him when they told him the cost
$1200 in K-36 , we primed & block sanded it 4 times
and the rest in sealer , DBU base color and global clear & reducers .
Now he knows what is involved in a $10k & up paint job is all about , he sure hated the block sanding through the courses of sand paper
I felt like I had a little kid in his garage saying " Are we DONE yet " after each finer grit ........ LOL
Heres is his car BTW , I just got done finishing the hood Friday , and installing it today .
