Thin (Reduce) DR Colorchip with Acetone?

Trying to perfect my technique of touching up road rash and minor scratches and have been experimenting with my airbrush needle sizes and air pressure, etc.


 


So I gave DRC a call and they said when they need to, they use Acetone as a reducer. Which has me wondering how safe that mixture would be if I used it on 'Plastic' bumpers. Granted it woudn't be very much, but thought I'd try and get some feedback.


 


And because I have some PPG DT885, the MSDS says it  contains:

LeMarque- Unfortunately I can't be of any  help with this...but I do find it interesting that you plan to do the DR ColorChips via airbrush.  What kind are you using?
 
Paasche - VL Double Action


 


Been slow so I thought I'd hone my skills. Using a paper punch, centering the hole over the chip, hit it, move to the next, come back, hit it again, etc.
 
Ah, I wondered if you use a Paasche.  I used one for plastic modeling back in the day and have never got it out of mothballs to try for this stuff.
 
Also, it seems to use less paint. That little 1/2 oz. bottle goes along way when reduced; which I'm still experimenting with to find the best proportions.
 
Ive done one touchup w an airbrush. Was using body shop supplied paint and thinned with acetone since no reducer available. I had emailed drc awhile back and if i remember, some of their paint is lacquer and some is urethane. I also talked with automotivetouchup on the same topic and theirs are mostly urethane but i think they also said to use acetone. Ill have to find all my notes on the topic because an airbrush is definitely a good method.

Thanks!


 


Would be great to know the needle size and dilution ratio you used.


 


Making more sense now to use Acetone with unknown paint formulas ...
 
I'm really following this, sure appreciate you guys doing the groundwork.


 


This reminds me of when Brad B. used an airbrush to touch up his Porsche; his (GREAT) results had an aura of "don't try this at home, kids!" for some reason, or at least that's how it came across to Yours Truly.
 
Again, ill have to double check, but i am pretty sure i was on the 0.3mm needle and i am confident that the thinning ratio was about 3:1 paint:acetone. Do note that all the touchup paints youll get will be different viscosities. The stuff i just ordered from automotivetouchup is fairly thin and ill probably spray without dilution.
