so a truck came in the other day with a fresh layer of under coating, i realized why haven't i done this to my gp. new england is tough on cars and rust sux. so i was wondering if anyone else has undercoated their gp and if so a affordable brand with good results??

My winter car actually have one from previous owner. Gotta thank to them. It does help lot. I don't see any rusty under it. Just some rusty tailpipe which it is normal for north weather. I do have little rusty where bottom side is for jack point if you get flat tire. Of course it was not on coating but rest of under car is great. If I buy new car and keep it rest of my car then under coating will be my 1st mind to start before it is reach winter season.

Any quality rubberized undercoating will do the job just get under there with a wire brush and clean up any loose crap and take your time do a section at a time.Chico(pops)

ok thanks chico

i dont use the ruberised, i use a paintable undercoat, seems to dry hard and not sticky

The trouble is the paintable cracks and lets moisture in the result more rust under the undercoating ,wereas the rubberized bends and stretches with movement and is less suseptable to cracking.Chico(pops)

just depends on where you put it, we painted an entire car with the paintable stuff lol

The ashfalt UC stays sticky but the rubberized dries up dry to the touch the paintable UC is usually used on the rockerpanels and such.
