anyway... what do you mean muffler burn? did your muffler come in contact with the paint or yung black soot lang?
if it's the black soot, your solution is quite simple lang coz what occured is the carbon deposits have accumulated on your painted area... while the solution is simple, it may not restore the paint fully coz pinatagal mo na eh...
you can clean the area muna with soap and water, then follow up with kerosene or a good water based degreaser. This will take a long time coz you'll have layers and layers of soot to remove (much like engine degreasing), after that your paint will look whitish and dull... At this point, use a good cleaner like 3M Finish Restorer or Meg #66 or EO Finish Restorer to remove the haze then repolish and wax...
Also, this may never have happned if your engine is working properly... Your exhaust shouldn't be emmitting (sp?) black smoke/carbon so much for it to stain your bumper. Have that checked as well...
If it's not black soot and burnt talaga, ignore what I just said and have it repainted :P
8) guys ganyan din nangyari sa bumper ko....naging brown yung bumper ko dahil sa smoke ng muffler....what i did is i applied 3M scratch remover....and natanggal sha....ofcourse follow on polish, wax.....ok na.....
