    How long to you wait between coats for flashing?

    That will depend on the brand of paint you are using. A lot of them require about 5 minutes between base coats, then wait 30 minutes to 1 hour before clear coating.

    Hi great vid. I have a quick question. I'm currently doing an on frame restoration. I've had lots of rust to deal with. I've sand blasted the rear hubs that the final drive half shafts go into and I don't know how to paint them best. Do I put them into epoxy primer and then use a acrylic enamel paint on them or should I use a high temperature paint for the hubs, such as a brake caliper paint? Thanks James

    Great video , I recommend drop coat all metallic paints , ( reduce your pressure and increase the distant between the gun and the panel and just let the paint drop ). Not too low of a pressure then you will have the drops of paints just perfect enough make your hand dance just from your wrist . Good luck .

    I would probably see what high heat primers and paints are available for the hubs. Dupli-Color or Eastwood make some products that will work for high heat application. I am not sure how hot hubs get, but it's better to be safe than sorry. Thanks for watching!

    what do i do if my base coat is an orange peel, a little rough to touch due to the dusts that the wind carries, since i don't have a paint booth and i'm just painting outside of my house, its glossy though but not that mirror glossy since i haven't put on a clear coat yet. Do i have to sand it out or just do the sanding after i put on the clearcoat to make it smooth as possible?

    While I understand how to avoid motteling on base/clear and on tri-coat, what would you do to prevent motteling in a single stage scenario?

    Can the wrong reducer cause this as well, and how to no which reducer to use?

    from what someone told me; mottle/ing is when the metallic flake  is tumbling around or floating in the reducer/carrier and flattening out. or when you hear someone saying "standing the flake up"  or dusting after you've sprayed it can cause blotchy-ness or flakes laying flat  making the "flop" uneven.  air pressure after your dryer/desicant set up is critical, too much air pressure at the gun  or trying to work too fast will cause flakes to lay flat as well.

    reducers doesn't cause mottle,but you have to mix metallic paint 2:1, you don't put you coating too wet,you put your gun around 25psi and you mist the paint,drying time depends on the weather

    I just finished my 3rd coat of dark metallic grey paint and it looks like rows of shiny, and rows of darker color :(. I am hoping the clear coat would mask it since it's dark grey?? Any ideas other than repainting?

    Thank you. Fantastic information. I had this problem on an older Infiniti. It was my first repaint and plenty of trial and error. I had no idea what was causing the seemingly random blotchy areas. I couldn't even locate the term for what I was seeing.

    I was indeed spraying the base coat too wet and not allowing enough time before clear. This is outdoors under a car port in Florida. The humidity was wrecking havoc. Not until I checked weather reports did I realize that early afternoon is lowest humidity here. Once I learned how to dust coat, and to do my work in early afternoon, the problem went away. I had to treat the hood three times.
