Ok guys! i will update you on my latest DIY project.
Lately i noticed considerable road noise. I checked under the rear wheel wells and found that the black stuff have stripped away leaving the metal exposed.
Went to ACE hardware (again) and bought myself 2 cans of Mar Hyde (you can use other brands too) RUBBERIZED UNDERCOATING.
i used newspaper and masking tape to cover the area surrounding the wheel wheel and wrapped up the suspension with newspaper.The tires need to be wrapped too.
i jacked up my car, wrapped a cloth over my nose and mouth, and sprayed the whole wheel well. 1/2 can per wheel well. I did it yesterday morning and it took 24 hours to dry.
Today i checked but still not satisfied with the thickness so i decided to spray 1 more layer. Should dry just in time for me to get to work. i will do the front wells next week because its tiring and the stuff takes forever to dry.
Will update you guys on the results tomorrow!
Tips: That undercoating stuff is nasty. Don't breathe it in. Even with the face mask i felt dizzy and had to stop after doing 1 wheel well. Also, don't be a hero and empty the entire can on 1 wheel well because it will take 4 to 5 days just to dry if you do that. even a 1/2 can coating took 24 hours to dry lol.
Also, use another jack to support your car as backup or use a car stand. Sometimes car jacks can fail. Safety first.
