I'd like to redo the undercoating in the wheel wells, to help prevent rust. I was just curious what everyone has used? I tried spray undercoating before but the stuff peeled right off. I wasn't sure if something brushed on would be better or not. Please let me know some good products.
I searched undercoating, but everything was powder coating topics.

Thanks.

 

I use some undercoating that you can get at about any parts. I think its made by dupli color but I'm not sure. It comes in a blue can, qt or gallon. It is made to either brush on or a kit for perfect texture and includes a roller..

 

what about the Rhino truck bed lining? sprayed on? My buddy does it, idk why im posting this it here

but bump for this thread

 

3M rubberized under coating.

Its in a rattle can, i used it and worked great. Looks almost OEM.

You have to prep before you spray, which is probably why the old stuff peeled off. Its a very long process to prep the underside of the vehicle.

 

I used the 3M of Duplicolor stuff every few months. It's meant to be a sacrificial layer, so if you don't want to do any upkeep, prep the f'uck out of it and have it Linex'd for ~$500.

 

Cool, thats what I ended up buying today. This is mostly for the wheel wells. What do you recommend for prep besides the obvious washing?

Thanks!
