I was using a paint gun to spray my engine compartment with gelcoat. Most of the gel ended up floating away in the air and little was actually making onto the surface. I did some surching and found this. http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WDVW

Man, what a difference. What took 3 days of spraying with the other gun took 1/2 hr with this one!!! It really put down the gel.

you can buy larger needle seat set ups for sata as well as most brand name guns at your local paint jobber. so you can use one gun for any product you wish to spray. you can also get the disposable plastic cup liners that are great for spraying products with a short pot life life gelcoat so clean up is quick and easy should the product snap and cure in the cup. ratman

I could not find diff. tips for the guns I have so I just went and bought a whole gun
