means I'd have to come all the way back to come and collect it! I suppose I could always stay over yours or something? How long would it take to dry?
well you would have to come all the way back anyway cos you would have my car lol, and you are welcome to stay here any time for as long as you like so that is not a problem
as for how long it dries?
my dad was looking at the new honda civics when his old hyundi gave up, (he went nissan instead YAY!! lol) we had a look at the cars and i got under one of the brand new ones in the show room, the bottom was covered in this thick black tar, stones were just getting absorbed by it so they had no chance of scratching it, thing was tho it was still wet, even after it had been put on in the factory and driven to the show room! the sales guy said it takes a very long time for it to dry, but in a way its not ment to ever be completly dry because when it dries it cracks and falls off.
so i suppose it depends what you get tho, i bought some sound deadening spray from halfords, it was expensive crap! but it left about a 2mm thick chalky surface that was soft and stones get slowed down by it. it would have been perfect for underseal if it wasn't so expensive.
i would talk to matt, he said there is something he puts on the cars after under body work,
but also just a few layers of standard primer will help, the more layers of anything you have on the bottom of the car is going to help protect it
