Thinking of getting a bit of prep done on the underside before winter hits. Heard some great things about this stuff...

.and perhaps a gun to apply (exactly the same as the Sealey SG18 but not branded) ....

Anybody done or thinking similar??

Also look up raptor liner, as used by stevie.w in this V10 build

Thanks, will look that up. I know the usual waxoil types of underbody sealer have had some bad press of late with peeling off and water getting in underneath which just exasperates the problem.

I think on the Z4, the brake pipes are the most vulnerable.

BH have a new product coming out. This thread is with a read:

Been using white grease for years and never had a problem with rust/corrosion particularly around brake pipes. Its fairly cheap in a rattle can and doesnt wash off like other products.

BH stuff is pretty don. I use an aerosol of Dynax on the underside & lower half of my rally car. It seems to hold up fairly well. Be warned if using it on anything visible though - I'm sure they will tell you is dries clear, but it's actually got a yellow tint to it.

The Bilt Hamber atom-mac has now been released:

Very interesting. Few questions on that thread which would be good to get the answers to.

I've never really thought about protecting the underside of the car until i saw Forensic Detailing youtube video [think it was his winter prep video]. If i recall correctly however, he basically layered fusso coat on the underside quite thick using a bit of sponge. However, this bilt hamber stuff looks quite good. Possibly ACF-50 could help in certain places also.

His videos are long but im guessing full of good advice lol. I can't watch them without skipping a bit!
