Painting strips over sanded clear coat

I based an clear coated my hood about 48 hours ago, 2 wet coats of clear. I need to sand down some imperfections so I'll sand the whole hood with 600 or 800. I want to paint some black strips around my hood scoop, then clear coat the whole hood again.Will I be ok painting on top of sanded c/c.

I see your in Texas, hope the weather is warmer than here.

Clear coat and curing are temperature related...if the hood has been inside where the temperature has been warm, say 65 to 75 degrees, you should be fine to cut he clear with 600, mask off your stripes and apply color and reclear the hood.

What clear, temperature of harder and reducer did you use?

Summit heavy solid clear & mid temp hardner, no reducer. I have another question,when I spray my c/c I've read that reducing the clear will help it lay smoother. I have mid temp & slow hardner also have mid temp & slow reducer. I think I can reduce up to 10%. What combo would make it lay flat, it will be into the 70s today. Also have a 1.2 tip for the gun, I was using a 1.4 when I shot the clear Sunday. Would a 1.2 do a better job.

No, a 1.2 tip won't do any better, as you mentioned, you have a heavy solid clear and need the 1.4 tip. I personally don't like adding reducer to clear if it doesn't call for it in the mix and only as a side note stating that you can if required. With a 1.4 tip, there shouldn't be any need for more reduction...all clears have solvent in them, some direct from the manufacturer, other's the manufacturer requires you add reducer when mixing.

Laying down clear is a combination of gun set up, air pressure (as recommended by the manufacturer of the paint gun) and technique. Most often, technique is the culprit if clear isn't laying down the way the person applying it likes...especially when air pressure and gun set up are properly done.

It's a big hood at least to me it is (78 Camaro). All the outer edges the clear is smooth as glass except for tiny bugs that landed on it. It the middle of the hood where I was having to reach over to, just a little O.P. Having to watch out for my shirt an air hose not touching anything takes my eyes off my over lap an gun distance. Now that I'm thinking about it I should start spraying in the middle an work my way to the edge. Thanks for the info.

Not really, start from the edge and work your way to the middle...then go to the middle from the other side and work from the middle to the outer edge...this way you will never have a dry edge in the middle.

If your worried about the hose, through it over your shoulder....if your worried about your paint suit or clothes, I take some 3/4 inch masking tape and wrap it around any loose clothing...that way it never comes in contact with the surface I'm painting.

And, tack off your air hose, I've seen so many painters take time to clean off a car and pick the air hose off the ground or if they have it wrapped around a hook on the wall, the hose has come in contact with parts of the hose that have been on the ground and that dirt will fall on your hood.

Hope this helps

Ray is right, it is a fine line between orange peel and runs.

It took a lot longer than I thought to sand down the clear coat, 4 hours, that stuff is hard. I ended up using 600 gr. wet sanding until I got a dull finish. When I was sanding I could smell that freshly sprayed clear coat smell, sanding it made it out gas a little faster. I didn't get to spray another coat of clear but I did spray two coats of jet black, they are at the base of the hood scoop an extend outwards about 1/4 in. One thing I had a problem with was making 90 turns with green 3M tape. I had to cut slits in the tape to make the turns. I forgot I had some 1/4 fine line tape, would that be able to make a 90 without having to cut it? I had some bleed thru at the turns mainly because I sprayed into the tape I should of sprayed on top of the tape. Anyhow now I have to sand them down a little an make them slightly wider to cover the bleed thru. Some time I'll get better at this.

It's all a learning experience, if you forgot that you had fine line and tried to turn corners with green tape, next time, if you have fine line you won't forget....if you don't have fine line...I'm sure that your going to get some. Regular masking tape can lift edges anywhere but it will happen mostly on corners. I use fine line for every stripe and or graphic...all you need is one spot where it lifts and it can become a delicate repair.
