Has anyone else had underbody protection applied to their car,I’m going to be doing mine in the next few week & using Bilt Hamber Dynax UC.Im just wanting to know how much roughly to buy,they do 750ml spray cans at £14.95 per can or their is 5 litres at £45.95,but what’s the best way to apply if I purchase 5 litres,the car will be up in the air on my 2 poster lift & I’ll be removing all plastic undertrays & ive got a compressor to connect some type of spray gun to apply.
2 cans is plenty. I took off the side skirts and all the underbody and wheel arch protection and used BH all purpose cleaner then sprayed it with Dynax UC.
