The trick with this method is to mask off the areas you do not want the nitro to react e.g. windows and exterior. Pour some fuel into a plastic container and soak some fuel on a rag and start rubbing into the paint (best wear some surgical gloves during this part). You will have to keep dipping the rag and until the paint starts to rub off. Remember you are exposing the fuel to soften the old paint so no need to go overboard. Use a cotton bud for hard to reach areas. This may take some time to do, so if you are going to do this over a period of days, wash the residual off and do not leave the fuel on the shell. It is also very tempting to leave the shell to soak in the fuel but do not do this as it will dry out the lexan and leaving it frosted and cracked looking. If you do have frosted areas it is not a real concern as you will not see it after you paint it but best to avoid it.
Here is a pic of the rear body mount area where it frosted up
The final result will depend on a few factors like the type of paint the painter used, quality of lexan, how much prep work they had e.g. washing and scuffing and also how thick they had laid on the paint. It may also appear patchy in areas...once again not a major concern. Once the paint is removed, use some wet and dry sandpaper to scuff the insides of the shell, this will also remove some of the patchiness and scratches. You will be surprise how scuffed the lexan can be but once painted it will still look good. If you are worried paint the shell white.....hope this has helped.
