Second coat

[Guest]

On just about anything I shoot, I seem to have good luck with first coat as far as how smooth a part turns out, but if for some reason I need to throw a second coat on, I ALWAYS get O.P.

What am I doing wrong? Whats the diff between 1 coat and 2 where this happens?

Distance about a foot to 14 inches, Ground is good, to grounding rod as previously posted. KV's around 20 to 25, and I even put on a fresh hook so the ground is right.

Re: Second coat

letting the part cool below 200*?
building to high film thickness?
I like to let the part cool, and place a nice even coat light second coat, unless there are some crazy Faraday areas, then I shoot the Faraday areas hot, wait to cool, shoot the rest.

Re: Second coat

Thanks man, I do let the part cool all the way down (wich is still abot 100 degrees here in central Florida). I could very well be shooting it on to thick the second coat, but it seems to me Im doing the same as the first.

Re: Second coat

But are you saying you put the second coat on thinner than the first? Cause I shoot the same each coat (or at least I try to make it the same)

I lay them about the same generally.
I lay the second coat on cold (below 200*) then apply the second coat at 12-14 inches gun to part distance, and at 1/2 the original coats kv's.
applying just enough to not see the original color anymore, then check for light spots with a flash light.

DISCLAIMER!!!
THIS NEXT TIP TAKES ALOT OF PRACTICE, AND SPECIFIC POWDER KNOWLEDGE DO NOT ATTEMPT ON YOUR CLIENTS PARTS UNTIL YOU HAVE MASTERED IT!!

Some colors (transparent/candies) on the second coat I apply as above, put in the oven until the powder just starts to gel (usually about 2 minutes in my oven) then pull out and inspect for color consistency, if I need more color in a spot I add it, and fully cure.

Re: Second coat

If I understand you right you are putting the second coat on thinner than the first?

I like my base coat to be around 4-7 mils, and top coat as close to 2 mils as possible, hard to do by hand, but thats what I try to do

Re: Second coat

Sorry mixed up my reply with a different question else where.

Try again, I do pretty good on the second coats. Flat stuff is my real issue.
