RC Body

[Clem]

Shiva



got 2 RC bodies given to me, want to try some Auto Air out on them.. on the OUTSIDE, just like a real vehicle..
how does one clean them? primer?
and do you top coat it like a car paint job with some? form of clear?
this is not necessarily going to be actually used ON a RC car, but is more for practice..
Thanks
John

Not real sure with AA but I'm thinkin
I'd wipe it down real good with alky first !!!
See how it holds before thinkin clear !!!
If it holds,,, a rattle can clear would
work on top of AA !!!

What I know of clear lexan or poly bodies, is...

wash with warm water and mild detergent to remove minor oils and greases and most importantly any release agents that may have been used in the molding or vacuforming .

once thoroughly dried, the bodies are painted from the inside.
This not only requires no clearcoating but protects the paintjob from damage.

do not clean the bodies with acetone, thinners, reducer, etc!

Posts: 6 Thanks for the advice.. I cannot think 'backwards' as the inside requires, and as these were just to paly with, wasnt too concerned with durability as is the norm
Washed the heck out of them in heavy duty detergent, let them dry a day and uses Fusion Satin White as a primer, let set for 24 hours and it wont fingernail scratch off, so next will be priming with AutoAir dark, and tehn go at it..

AA works really well on the polycarbonate. Normally just a good washing is enough and adhesion is good. Scuffing the body with Scotch Brite help promotion if needed, but never when using Chrome.
Since your painting on the outside, just a good quality clear spray bomb will sufice. Something like Dupli Color Acrylic Lacquer works great. Or Krylon crystal clear.
However, If your pacticing to paint more bodies in the future, you should go ahead and learn to paint them from the inside.

[Shiva]

ok, I got a fubar.. truck primed with Fusion.. waited a week or so,, washed the heck out of it, to make certain it was still clean on outside, then primed it with
AA basecoat.. heatset with hair dryer.. then put pearl white on top..
heatset AGAIN..

so far so good..
then mixed up some candy per instructions, and coated again, heatsetting between layers.. let THAT Set for some time, just for certain, and then used some transparent clear on top to smooth things a bit and HEATSET AGAIN..


laid out a flame on the roof, and goofed up..ok, before setting,I took plain water and washed off the flame goof..size of a quarter..
WUUPS, washed off EVERYTHING down to the pearl white with plain water? it happened.. now wondering WHAT happened..
and WHY..
teh pearl is in perfect shape still
was doing another body at same time, same base coat, different top coat, and its fine, held perfectly.. took rattle can Duplicolor and clear coated it, and no problems..

[Maxx]

Were these all AA? What was the trans clear you used before the flames?
I would use the Duplicolor over the final base before I start any artwork.

[Shiva]

yes, all but the base primer AA

what I dont understand is the layer between the candy and pearl white not holding..
washed off with plain water.

[Maxx]

I'm no expert on AA, so my only educated guess would be that since AA is water based, water being the solvent, when you reintroduced the water it resolublized due to your mixing and how thin (lack of pigment) the candies can be.

Again, to be on the safe side, I would use something like Krylon crystal clear or Duplicolor acrylic lacquer clear over your final base before moving on to your flame or other artwork.

[Shiva]

but, its NOT supposed to tho.. the heat setting should prevent that..

[Maxx]

LOL, if only life was so simple!

Your right, but even though, things don't always work the way they're supposed to.

What kind of mixing are you doing to the candy? Most AAs are ready to spray straight out of the bottle. Unless you are adding UV protectant?

[Shiva]

per dixieart.com
AB 4004 Transparent Base, with UV protector
Use as base for mixing with 4600 Series Candy Colors and as mid-coat. Prior to clearing, use as a filling, mid-coat (inter-coat)over other colors as fill coat over large pigments and flakes for more even paint film, especially prior to clearing 4500 Series and 4400 Series Colors.

Dye-based transparent colors. Apply over 4100 Series Aluminum Bases or 4300 Series Metallic Colors. Candy Colors are concentrated: always mix 1:1 with 4004 Transparent Base to lessen the intensity and to add UV protectant.


it failed..

you were doing another body at the time with a different topcoat.....what was the variable that made that one work and the other one fail?

[Clem]

I use AA paints also. Being new to this I use a damp paper towel to touch up some of my mistakes regular. Heat set or not the AA always comes up with water. Just part of the water base setup. That is part of what I am trying to figure out about wiping down between coats. Can't use anything moist.

well, different top color.. not the candy.
base coat, plus a metallic blue over that, and it held.
then clear coated with Duplicolor Clear Coat-similar to whats used on cars..
Its sold at the local Walmart in the touch up paint section in automotive.

ok, question then.. the paint OVER the recommended base coat was pearl White AA. it held up PERFECTLY fine to the washing..no bare spots at all.

plus the 2 glass windows I am doing also have held up to scrubbing with a mildly rough wet rag.. not a harsh scrub, but I had to get a drip off plus some accidental mess made in one area. and it removed only the one layer that I ahd not heat set pretty good.
inquiring minds are now curious.. AA web site does have a 'paint remover', 4008 IIRR, that will remove any dried on paint no matter heat set or not off, so you can start over but I keep that far away from the painting area and do not use it even in the same room.
