Underseal/Wax

[Sie!]

Hi all,

Just wondering what people use as under-seal and cavity wax. There's so many different products out there I haven't the foggiest which is best, or even had much experience with such products.

I have been touching up the under-seal on the sills and underside of the car for a few years with the black Hammerite waxoyl stuff that I apply with a paint brush, but I have seen various products that can be sprayed on to give a more comprehensive coating.

What do you guys use, do you have any recommendations or cautions?

I would also like something to spray into the box sections of the chassis and sills, I noticed when doing the subframe there's some rubber grommets/bungs etc that can be removed to gain access, I would like to spray something inside if possible.

Any thoughts?

As always any suggestions greatly appreciated.

Just make sure you cover the garage floor well

As John says, Bilt stuff is very good. Rustbusters is good as well.I have used both and no complaints
