Yes you can,
but PREP PREP PREP is the key, to get a nice job that will last you need good quality paint, plastic primer etc, no cheap stuff,
and your final result will come down to how well you did your prep work, prep work is 70% of the job,
if you havent done much painting, than i say seriously think about it first, cause it can so easily turn out crap if you can paint properly, and a DT175 with crappy painted plastics will easily half your sale price if you ever wanted to sell it,
