got 2 cars to fully underseal,1 is down to the bare metal and the other has a thin factory paint coating (jap import).
Don't want to ever have to do this again to them so want to use the best stuff 1st time round.
The car that's down to bare metal will be getting top coat once it's been undersealed,the other won't be but neither will see winter roads.they will be used but not all year round.
Can anyone advise what/who to use??
Thanks in advance,lee
