What Underseal should I use??

Hi there I want to underseal my 2002 jimny and am wondering what’s the best underseal to use I have already purchased some rust converter to put on first thanks.

If you are keeping the car, don't use a pitch type underseal that doesn't dry. They are a bugger to clean off for further repairs, later down the road....

Buzzweld gets rave reviews but is a tad pricey....

Hi,
I use a Tetraschutz type underseal, but spray it on using a Schultz gun. I only use this to repair the OEM high impact areas, but only after all the rust has been removed and an anti rust primer has been applied.
BUT I would not use it as an anti rust covering on the underside of my Jimny, for this I believe you are better using a wax product. I favour black waxoyl as a covering direct, it works even better direct to rust converter. I have seen that it does keep further rust at bay and does not hide any further rust that may develop.
Plenty of wax products available, any is better than nothing, so you can't really go wrong.

Here in Norway the only products really competing with wax / oil based products is either lanolin base or linseed oil base.
Some products that form a too hard shell will crack faster and not seal, some products too soft will wear off faster.
Most important is to do it and not postpone..

I used a brand called BILT HAMBER. Top stuff.

I used a fat-based product Mike Sanders. I think it is great, especially if the area is not new, but whenever you do something to the car`s underside your handy get full of fat.
