clear coat application problem
Hi All,
I'm having a problem applying clear coat to a 65 Mustang that I am rebuilding and am hoping that someone can help me figure out what is wrong. I'm using an HLVP Finex gun with a 1.4 mm tip with a pressure of ~40psi at the gun. Based on assistance from a member of this group to an earlier question, the colour coat is going on very well using a gun distance of between 8" and 10" and a fan size of approximately 11". I'm using the same gun settings / distances to apply a 4:1:1 clear coat mix made up of DCU2042, DCX61 hardener and DT885 reducer. The problem I am having is that the clear coat finish is very dull looking and has a 'rough' feel when you rub your hand along it. Any help / suggestions that anyone can give will be greatly appreciated. |

Dryspray problem. I'm not sure what preasure we use at work but I think
it's closer to 30-35 psi at the gun. Could also be you're spraying at too fast a pace. Medium wet coats like the base and 2-3.5 feet per second spray speed same height as the base spray. Good thing that all you need to do to fix the clear is wet-sand the surface to take out the worst of it and re-coat. That's about all I can offer now as I'm on holidays away from the hell I call work and can't ask any of the clear coat applicators.

Hi D.J.
Thanks for taking time out from your holiday to make comments / suggestions. I'll try cutting back the pressure and slow down a bit and see what happens .... |

Check your volume too. Disconnect the air and just run the pot
preassure to test and you should get between 3 and 4 ounces per minute. They use a cheep pyrex measuring cup at work (easy to clean) and time for 15 seconds. Most spray at 3 to 3.5 but a couple spray ar 4 ounces. That should also help.
