How to Underseal Your Car: Long Lasting Rust Prevention (BILT HAMBER)

[@wirries]

good stuff & nice gti! couple tipps to take it to the next level: tape off breaks (and maybe upper body if you have the patience/material), beware that anything that gets hot (exhaust, motor area) is a no go for the simple sprays as they will melt off / over heat / create strong smells... there is specialiced spray for that. oh, and tape off any sensors. some people also take off the wheelbase protection and spray under that (often rusty as it gets dirty/wet/rustry despite the protection).

Cheers! Some really good builds there that I hadn’t considered. I tried to avoid the high heat areas (well at least directly) but there will be always overspray. I didn’t actually film it, but I did get some to pull back the arch liners and get some protection sprayed down. Definitely needs a dedicated weekend of preparation to really get the car ready!

I only have a jack, what would be the best way for me to get clear access under my car? Did you get much spray back, just thinking if I’m under the car am I going to get covered in the seal?

You could definitely do the job with a Jack and some axle stands. I’d definitely recommend a set of small drive up ramps to make life easier. And a mask and some googles especially if you are working without a lift - spray back wasn’t bad but it is an aerosol so you need to be in an open space. Hope this helps!

I did this job with 2 small ramps to drive the front wheels up, then jack the rear up slightly higher than the front to get the car nice and high up. When the rear was up I took the wheels and arch liners out, cleaned whole underside then sprayed the next day. I got covered in spray so I would recommended overalls and safety glasses
