Undercoating Question

I have all my F-1 parts painted and ready for assembly. I want to undercoat the fenders and am thinking of spraying them (rattle can) before assembly. Any pro's or con's? I am also looking for a recommendation for a rattle can undercoat that drys fast and firm and doesn't remain sticky.

I plan on using Herculiner under my running boards and fenders. I used it in my bed and like it a lot. It is much tougher than undercoating, so I expect better protection from stone dings.

For the bed, I cut the corners in with a sponge paint brush (dabbing it), then rolled it on the larger surfaces using the supplied roller. I'll use the same technique under fenders and boards.

I used a product recommended by my painter. It is "Dupli-Color" Truck Bed Coating.

It comes in a spray can and goes on very neat and even, I sprayed it on the bottom of the cab, the bottom of the running boards, and the insides of my fenders.

It is not as heavy duty as Herculiner would be, but goes on neater and seem to be doing the job protecting my rear fiberglass fenders.

I would do it the same the next time.

There are two products that were available and I was told to not use the "cheap one". I spent somewhere around $5 or $6 a can. I bought it at a local Autozone.

Thanks all. I think I will opt for the Duplicolor truck bed coating. Wish me luck.

I have used a 3M product called "Proffesional Grade Rubberized Undercoating" with good results. It sets up hard in a few days and seems to stay put. I have only found it at auto paint suppliers, not the local Wal-Mart.
