Post subject:  What to do with overspray?
I just tried laying down my first coat of paint and it seemed like i was getting a lot of overspray, like snow. What do i do? do i wait until it all dries, sand it back and start again, or do i keep going and when i block it back later it will be ok?

How do i get a really wet finish? (dont even think about saying anything cush)

And what do you do if you get a bug/insect landing in your paint?

Is it over spray in the air, or a rough overspray covering the panel surface?

if there is too much overspray you may have your gun pressure adjusted too high, i had mine regulated for about 50psi, or maybe too little thinners in the mix, or even if you are holding the gun too far back from the panel.

Theres always going to overspray in the air but as long as what you are sticking to the panel is wet, should be ok??

I didnt worry about all the overspray in the air, as long as the paint was going on smooth.



To get the wet finish you are after, you are supposed to with each coat add more and more thinners, some say to end with a coat of 90% thinners 10% colour.

Its more that there is a layer of overspray on the panel forward of where i am painting. The paint seems to be going on ok, i'm at about 70 - 30 at the moment and its coming up glossy enough for the moment - but the rest of the roof is left with this crap on ti.

yea i sprayed mine up like that,a fine layer of spray dust over all my beautiful panels, it doesnt seem to have caused any adhesion problems.

The fan idea would probally work abit.

Hopefully someone with a bit more expertise will have their say

r u spraying with acrylic or 2 pac

If acrylic, dont try and get a glossy finish on your first few coats,,, infact the first
few coats should be very light, dont aim to cover a panel with the first 1 or 2 coats.. do it nice and slowly and then on the final few put the paint on a little thicker and it
will be a much better finish

Make sure you start at the drip channel then work towards the centre as far as you can go. Then move around to the other side of the car and pick it up from where you left off and work back out to the drip channel. If your a little slow moving around there you will get a bit of a dry patch down the centre. If its acrylic no biggy you can just wet rub it nice and smooth later. If its 2pac forget everything I have just wrote as I have no expeirence with it :o
hope it helps a little

I assume you are using acrlyic? Painting isnt the easiest thing to do, there is a lot to it to get it right. anyone can get a crap job then sand it back, thats easy. The skill is getting it right off the gun. I cant stress enough to you guys get some advice first. There is so many variables. Air preasure, paint volume, gun angles, distance from panel, spray fan, gun speed, air compressers, guns, the list goes on and on, Take it from a panel beater spray painter, it looks bloddy simple but there is alot to it.

If your getting dry spray it could be you have not enough paint volume, gun is to far from panel, gun speed is to fast, guns speed to slow, wrong type of thinners, cheap and nasty gun. It is hard to diagnose a problem without watching you do it...

You can keep painting and block it back later if you want, just takes longer.... Preperation is very important make sure its masked up properly and have a good time.... PM me if you like and ill do my bst to help you out..

acrylic paint is almost impossible to get a perfect finish straight off the gun. I have a $230 gravity feed star spray gun. It uses very little air to atomise the paint, 45psi at the regulator with the air control on the gun wound back about half the way. So actually using about 30psi. I hold the gun about 8 inches from the job, and have the fan set so the spray patterns about 6 inches wide. I over lap each coat by about 30%. Doing it this way I got no overspray or dry patches on the smaller panels and only a little on the roof. No biggy, 2000grit sand paper and a bar of soap and a hose will fix that wit minimal effort, not what i would call sanding it back, more like a light rub before you run the polisher over it.
well thats what I think anyways :o I will post some pics when I polish mine up.

Thanks for the help guys, I'm also using a Star gun. Seems to be ok. I think i've started on the hardest part of the car, the paint gomes out perfect when i have a couple of practice goes on a drum that i use. I can see now how going from back to front is much better than going from side to the middle then side to the middle again. I'll see how i go with the vertical panels, i've feel that it will be a lot better.
