help with, after sanding and b4 clear coat
Posted by DDD on Sunday, May 26, 2019 7:23 PM

I've color sanded after a crappy paint job, is it ready for clear coat? or do I need to sand it down more? I'm afraid of sanding thru like I did. How to fix the sand thru? paint the whole side again? or mask of the mistake and paint just that little area? and the re-sand. I appreciate any help. Thanks.

Its hard to tell from the photo but it looks like you sanded to far down to just clear it now. If you do sand into the primer you can easily spot blend those areas, just thin the paint and close down the needle and lower the psi and slowly (very slowy) spray fill these areas and build it up till its fully covered. It should take many light passes and  paint at a much closer range than you would do if painting the whole body and then lightly wet sand the area to blend it in, then clear and when done you should never know where this was repaired. This is done at full size body shops every day.

I have been following your posts and I'm just not sure where your problem is caused by. Most things that I would say should fix this has been brought up and sounds like you have been trying.  Its a long shot but is this the same jar of paint? I have never had a bad jar but without being there its hard to see what the problems are.  Is your ab still spitting after you cleaned it? The paint just looks so grainy that it almost seams that some thing got into the paint, but it maybe just the photo. Good luck and stay with it and you'll get it fixed.

From the looks of it, you need to spray the whole body again to get the paint uniform. If you're going to spray clear over it, spray one coat over the paint before you sand it. This will give you a slight buffer when you sand to spray the other coats of clear. It will also let you know immediately when you sand through it. The moment you see color on your paper, stop sanding even if it isn't smooth. Remember,  the last coat of clear is the one you'll sand smooth and polish.

Thanks Viperdoug and Plowboy for your help. Just need to keep practicing and trying different methods and paints until I find what works. It's hard to tell what's correct and what needs fixing and when mistakes happen what was the cause. I tried to repair it then clear coat with MM lacquer clear coat and after a few mist coats I could not get a wet coat to go down. even turned down the psi and open the flow and still no wet coat. What's is a good clear that I can use everytime on anything? Thanks again for the tips.

I use nothing but 2k clear.  The first time I spayed it I was just blown away by how nice it laid down so much so that some times  I don't even wet sand and polish.  Try Splash Paints so you can by a small bottle of it to try.  I know some people are against using it but I spay so little every year and have a good mask and spay booth I feel its safe for the few times I spray a body per year.  With MM lacquer clear that I found that to get a nice finish that I needed to spray a heavy wet coat and that it was hard not to get runs.  I found that I always need to do wet sanding and a lot of polishing to get a nice finish. And its not a hard finish so it was easy for me to polish through the clear coat, thats something not easy to do with 2k.
