Dinitrol 4941 BLACK UNDERBODY WAX 3 x 500ml AEROSOL SPRAY CANS

Very good stuff but wear a mask. Read the back. It's not a can of spray paint. You don't want to be breathing that in either, but especially not this stuff. Mask up and it does the job very well indeed.

This is by far the best underseal application I've bought (I've had 5 different types now) Goes on really well and is strong and flexible but not sticky and wet like the rest of them. Remains to be seen if it'll last but the finish is very good.

Best under seal lve ever used 100%

What to say its black wax to help keep rust at bay. For Black wax typre underbody its got to be this or BiltHamber's 'UB'. IME Dinitrol do some very good products. It's waaay better than waxoyl stuff, but do be aware it is a waxy product, so not totally gravel rash proof or really for high impact areas for which you're probably better of with their 445/447 product, but for other areas it is great :-)

The photos I've attached say 1000 words like my old art teacher would say and the product leaves your car looking like a painting! Photo one is before* and photo two is after treatment!

Easy to apply, covered better than I expected

Sprays on very easily, even upside down and only produces drips if you're over zealous. Lasts longer than expected too. Had to do the spraying when 10 degrees outside even though it says a minimum of 16 degrees on the tin and still went on well. It leaves a thick black waxy finish which covers evrything well. Guess time will only tell how well it performs but certainly application is a breeze. Recommend wearing goggles and something over your nose if working upside down under the vehicle.

Better than waxoil, easy to apply, lasts ages
