The exhaust yellows the paint on the tailgate. I can't rub it out, only by using600-1000 wet papet can I get it out 2 coats of wax. I have tried everything. help | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | yer problrrm is them tips that barely peek straight out - should be angled down and outward, to keep the exhaust from swirling back up against the gate .... but that wouldn't look so cool eh?  better than the grass skirts on the back of RVs tho!!

I need help here. | | | | | Joined: Mar 2006 Posts: 1,703 Shop Shark | | Shop Shark Joined: Mar 2006 Posts: 1,703 | Gazim,
without looking it sounds like the clear coat is getting a good dose of fumes/unburnt fuel circling back against the tailgate and is discoloring your clear coat.
I would guess rerouting your exhaust tips will be the only cure ...sanding an waxin is gonna leave ya with a dead paint really soon (CLEAR COAT GONE).
maybe flaring the tips more out to the side to catch the free flowing air as ya drive may be an option or double check your Carbs mix and motor timing to get a cleaner burn ?

with ultra-fine to wet sand Your problem out...As Bill said, if You
break through the clear than its repaint for sure...
There is NO strength in clear, and that is exactly why I always put color into My clear which gives it the ability to
cross-link...I am also talking lacquer color and clear...We had problems at GM with the white Corvettes, the clear would yellow, and it wasn't the exhaust because the whole car yellowed...The new
color coat and clear coat used today eliminated those problems...
