What are you guys using to undercoat the body?

Most are using a product from any local auto store, it is a rubber undercoat and sealer in a spray can.

Truck bed liner. My painter (streetrodpainter.com) sprayed it on during the body and paint work. It's great.

Typically most I know have done it in the wheel wells only to prevent spider cracks from
rocks thrown up by the tires.

Has anyone had any success with using any undercoating on the aluminum panels? Any prep work need to be done to them to have good adhesion? WalMart and a few local auto parts stores have a roll-on truck bedliner that looks like it may work ok. Ideas?

thanks

Just seal the underside of the body with a good cheap black epoxy rolled on first, then use the truck bed liner only in the fender wells in very heavy application for stone "checking" protection.
I would not use use the liner plastic all over for weight reasons and never over raw fiberglass surfacing.

I would NOT recommend the rubberized spray-on undercoat from a can. It provides very little protection and will melt like an ice cube on a hot sidewalk when hit with oil or grease. I got talked into using it on the underside of my aluminum and I've been sorry ever since. Use the bedliner. Mucho better.

grumpy why not over raw fiberglass?

since I have just completed the go-cart stage I am off to body work 101. I would like to have any seen underside of body painted to look a little better than raw.. Like engine bay...

it is a 2 part urethane epoxy that will coat bare fglass with no problems. you must scuff the bare fglass prior to coating. cheers, SRP
