Between a wet sand, and a Novus 2 polish, I went through the paint to bare plastic on a model. What do I wash the body with so I can repaint it?

Edit: I should add that I was hoping to avoid stripping the current paint, but I won't rule it out. Thanks.

70% isopropyl alcohol (not 91% or 99%!). It's a great universal solvent that should remove all contaminants without damaging the paint itself.

Do not use alcohol on lacquers of any type, or acrylics. Ammonia will safely remove polishes and waxes. You could use 3600 - 6000 grits in the micromesh polish kits too be absolutely sure.

Panel wipe, it's what's used in the auto repair business to make sure there's no Polish or anything on the panel before being repainted, your local auto repair shop should be able to helpĀ

Ammonia (or Windex) will also remove acrylics, but not lacquers.

Does Novus have any sort of wax or silicone content, or is it a pure polish (abrasive)? If the latter, it should be okay for repaint, though you might want to hit the polished paint with something like #800 sandpaper to give the new paint something to hold onto.

Novus must have silicone in it. I learned the hard way. I painted over a body polished with Novus and got the worst case of fish eyes ever.

Good to know!

I polish everything--plastic and paint--with Wright's Silver Cream from the housecleaning section of Walmart. It has NO chemical content at all, works purely by fine abrasive action. Love the stuff!

That's funny, I use Wrights Silver Cream too. Discovered it a long time ago when I ran out of rubbing compoundĀ :D

IF it's a lacquer you burned through and IF it's on an edge or a ridge(a wheel opening or a panel crease line) you may be able to blend in by brushing some of the color on the burned area.It will usually flow out and blend almost invisibly.I've done this a few times with Tamiya sprays and have had good results.

In the 1:1 painting world panel wipes (Prep-Sol, Pre-Kleeno, B-4, etc.) will not remove silicone. Been there, done that. I use TriSodiumPhosphate mixed in hot water to scrub any surface that may be comtaminated with silicone. Think Armor All...

Everytime I start prepping a car for paint it wash it with hot water and TSP. A couple of times before I start doing any paint or body work.

TSP is available at any hardware store, ask for it.
