Striping in paint
 
So I just painted this 8 ft camper shell&for some reason I couldn't get the paint to all blend together correctly,with it being so long it was hard to make the full pass.Should I lay it so its standing up vericaly or is it maybe gun set up?The rest of it looks awesome.
Thanks

cutthroatkid,

It sure would be nice to see some pictures so we can see what it is you are talking about.

It sounds like your paint may be flashing off between passes, is that what you are talking about? Or is it a metallic single stage and you are getting "tiger stripes"?

If it's simply flashing too fast you may want to go to a slower reducer. But fill us in on everything.

Looks like you need a slower reducer and less air pressure...

And also basecoat isn't always going to have that perfect look like you are leaving it that way, you are going to put clear over it which gives it a uniform gloss. But spraying it with a little more overlap, a little slower gun movement may be enough to get rid of those stripes.

As DBM brought up, what gun and air pressure are you using and what temp is the shop and the reducer?

Yeah, could be how the gun is set up or even the fan, on rare occasions. most likely what DB said.

hold the gun about 12-14 inches away from a test panel . It should look like a football pattern. If it's a figure 8 you are using too much air pressure, back it off until it is a football pattern. If it is small on top and large on bottom.. like a gourd there's dried material in the nozzle where the needle comes through.
Silver and gold are difficult to spray because they have VERY little pigment in the them. Mostly aluminum flake and binder. What happens when you spray these two colors the air pressure will separate the binder from the metallic. Most of the time it's a good idea to reduce the air pressure and do a final "drop coat" where the material will land uniformly and allow the metallic to land with the binder at all kind of different angles to reflect light rather that "plastering them to the car with high air pressure and little binder. You should use a tack cloth "lightly" between base coats to remove the over spray, if you do not it will not allow the other coats to stick and you can expect not so good news next time you go to the car wash. It will peel.

If you clear over it ,it will show...To fix it you should sand any roughness ,usually the light spots will be a bit rougher. ,so give it a quick ,light sanding and hold the gun a little closer so your spraying it a little wetter and (heres the trick) now spray in the oppisite direction...you were going side to side ,now you want to go front to back,back to front...say goodbye to stripes...
I'm not sure what kind of base your using but I had a lot of trouble with Omini doing this and had to go with slower reducers also...
