Noob single stage painting questions

Ok so I set out to paint my daughters truck with a single stage metallic polyurethane and it looks good in certain areas but in others I have alot of orange peel and to help make things look even better I put a couple nice runs in the last coat. So now for my questions,
1.Can I fix the runs and clear coat it. I know this defeats the purpose of s/s paint
2. Or should I fix the runs and get some more paint and just work smaller areas now that I have the truck pretty much covered and try and get a better coat on it..
3. I know your not supposed to wet sand ss but can you then clear.

 

I'd say that given your limited paint skills , plan #2 would be your best plan. good luck .

 

can't sand metallic without seeing the difference compared to the unsanded areas

 

Just to put a finer point on it for anyone else with limited experience who might read this, wet sanding single stage isn't the issue, it's done all the time. As LowKat pointed out, it's the metallic flakes that are the issue. They are "standing" at random angles, and when you sand them you affect the way they reflect light........gets ugly fast! As philly says, option 2 is the likely best possible outcome, but do you have the skill to match your original spray pattern/p*** rate/air flow/coat speed? This is one of those situations where the very experienced painter looks like a god, and the amateur learns some lessons.

 

Get ready for some pruney fingers and lots of cleaning. You should "block" that single stage paint all over. Maybe a paintstick and some 1000 wet paper. I like 1qt spritzer bottles for water. Once completely sanded clean it for another coat. When you think it's clean enough, clean it once more. You'll see the sanding remnats as things dry. At that point I'd over-reduce the color just a little bit and recoat the whole surface in a nice patient and even flow coat. You might need 2. A minor drop in air pressure will make it easier to control your metallic pattern. Let it flash an extra 15min and start the clear process. On some colors I'll mix my 1st batch of clear in the cups with remnants of my color. Sometimes it gives depth to the color, even silver. Take your time and put at least 2 more cleancoat p***es and it should look good. If you take your time and be patient you'll net great results. Pay attn to your gun settings too for the best pattern and finish.

 

highlander is right.The trouble you had the frist time ,just got worse.When you sand the runs you will sand off paint on each side of the run.Now you have a light spot to fight with ,so now you will have to be real becareful when you paint.Go slow,try to get some help,and pray.

 

Thanks for the tips, ill give her another try and take more time and not rush
