To sand or not to sand, Help...

Recommended Posts

To all modeling experts out there,

Do you have to sand "very minor" imperfection, i.e.: orange peel on the base coat (color coat) before applying clear coats?

or just shoot the clear coats over it and sand it down and buff after that?

I am using rattle can lacquer base spray paint, decanted and then airbrush onto the model.

Your answer is greatly appreciated. Thanks

Spraying over mistakes only make them worse. Orange peel still would be noticeable even after spraying another coat over it.

Good luck :)

in my opinion remember the simple rule ( the finish is only as good as the prep) so i would sand every coat prior to next coating

A finish coat is only as smooth and glasslike as it's basecoat . Take it up to 12000 under cold running water , lightly sanding , taking care not to burn through on the high points and edges .

Now , you are ready to lay down that mirrored glass shine with your clear !

Unless its a metallic or pearl color. You can't polish or sand on those. You have to clear then polish.

When you guys sand and go progressively finer, do you lay another coat of paint in between each sand? That would seem a little silly but thought I would ask anyway. I'm just at the beginning stages of my new model so I'm about ready to start the sanding process. I have 320-12000 grit.

no you dont... when i prep the body for first primer i start with 400 and work up to 1000... then primer, then lightly sand with 3000 prior to paint and after each coat of paint i use 2500 to level out the paint... same as with the clear coat... on the last coat of clear i use 8000 up to 12000 then use the rubbing compound to bring out the shine... then i use either wax or polish to deepen the shine...

hope that helps you out
