TIPS:Set yourself plenty of time and be patient and take you time, rushing causes melted ramps
Use an old ramp or bumper caps to practice on
Move quickly over area pause and see what is happening then move again
Use you hand under ramp to gauge heat
If possible remove decals
Ensure the ramp is extremely clean before flaming
The more wear you remove before starting the better your result will be
Dont be scared
DISCLAMER:
Undertake flame polishing at your own risk
I will in no way be held responsible for warped, buckled, bubbled, melted ramps
