iv got a queston iv got tiny holes where the welds were and i was wondering if i sprayed bedliner on the outside of the box if it would seal the tiny holes up
 
well i decided that the 1 1/2 in pipe wasent bigenough so i went to lowes today and got a 5 ft 2" pipe and hopefully ill get some more work done on it tomorrow
 
hopefully sometime this week im gonna try to get some bedliner to bedline the airbox and sorry i hsvent made any progress on it in a whine
