Hello, i'm a first time painter, painted my car and cleared the car. I have mottling or tiger stripes. How do I fix?
Do I just sand the clear with 600 and then reshoot base and clear or is there a different way. shooting bc/cc and paint is about 2 days old:confused:

You'll need to repaint the base and clear. Scuff the clear after it cures (but don't sand thru the clear) then apply your base evenly but don't apply it too wet. Remember that the cause of mottling is wet spots and you don't need to have the clear applied smoothly because your gloss is applied with the clear coat. Once you have the base on you should wait until it dries to the touch before applying clear. Applying clear while the base is wet can also cause mottling.

let me add to that make sure you overlap your spray pattern about 50%
and that will help also make sure your patern on your gun is even
i posted a reply earlier this week about this.
you can also spray some dust coats in different directions to even out your
metallics but not too dry you don't want a grainy look to your metallics.
Then let the base flash atleast 15mins or according to the manufacturer.
temperature will vary how long but like Len said when it flashes and is flat
looking and dry to the touch but be careful if you try to touch it if it's not dry
i usually try to touch some masking paper that has paint overspray on it to
test the paint if its dry.Then apply a medium wet coat of clear.too wet
and you can soften the base with thereducers in the clear and it can
sometims mottle the metallics.let the first coat of clear flash 10-15 mins
or untill tacky then put on a wet coat and you can let that flash if you like
and add a third wet coat for gloss and deepth.It's also good to put extra
coats if you plan on wetsanding and buffing the clear

When you sand through the clear then paint new color on top the exposed base may absorb solvent from the new base causing the edge of the clear around the sand-thru to wrinkle. When I sand through the clear I will either spray primer or clear over the hole, allow it to dry then prep and spray the area with base and clear. The primer or clear will act as a barrier, stopping the new base from attacking the edge of the hole.
