paint turns brown?

have a graco 5900 .got a aux light that plugs in . 1/4 jack plug in the control ,led light.from graco. for the machine.all it does is flash like a strobe.what would couse this?the light is about 3 years old,but never in service.we plugged it in about a week ago,to show a friend.and it worked well.mounted it on the 5900and all it does is flash like a strobe.what the he--. any help will help. thanks.

Does it make a difference if you turn up the idle? Ours blink sometimes if the idle is on the low side.

fast or slow idle ,does not make a difference.

Had a problem kind of like that. It turned out to be a bad ground wire.

graco is sending me out another light,put it on another machine ,and did the samething.hope they last longer than that.nice of them backing up the led light.now we can try some night time painting.

Why does my paint turn brown on seal coat. Im using w/ base white. Is it the heat? bad paint? sealed the lot 4 months ago.

I have had it happen on restripes I have done on others seal coat. I think it is the type of seal coat they are using?

Are you using an oil based paint or latex paint?

I use laytex

The only time i have a problem with latex on coal tar is if its really really hot and you stripe within about 24 hour of when you sealcoat. I made that mistake last year.....Sealcoated a commercial lot.....Striped 2000 parking spots, all hollywood style. Went back the next day to open the lot up at 5am and my jaw dropped. 2000 dirt brown parking stalls. And i only had one striping machine at the time......

We use Sherwin Williams Waterborne paint on coal tar all the time. We seal with 2 coats and as soon as the second coat is dry enough to walk on we snap lines and stripe, never had a problem.

ditto: SW Set-Fast Waterborne on 2-3 coats coal tar as soon as it is walkable (next day is better to let the sealer cure before it's under the stripe.) But either way never had a problem with SW waterborne white on coal tar or asphalt or new asphalt --any time latex/waterborne was need--always worked great for me. Most often your problem is a reaction...look very closely at the brown stripes (magnifying glass if you need one) and the "brown stripe" won't be brown it's white with lots of little brown spots or even droplets on top so that it looks brown. If this is the case it's your paint drawing the brown chemicals in the sealer out of the sealer to the top of the paint...if it looks like that (and I have seen it a lot) the paint is asking like a wick drawing the stuff to the top. Right paint/sealer combo won't do it (and it doesn't need to be way thick on sealer, the stripes usually last as long as the sealer so not overly thick w/paint.)

any tips on removing vinyl tape with a tar backing???
