I am building a revell harley davidson and their chrome is way too overpowering - I removed the chrome with fairy power spray, put the sprue or parts into a plastic bag, make sure they are covered in power spray, seal bag and leave over night, wash off under water and light scrub with an old toothbrush and its all come off - I would suggest testing a small part on the RTR model as the chrome finish or underlying plastic may be different to Revell's
Cheers
