Undercoating bottom of hood?

[Aarons72s]

The spray can bedliner, duplicolor, definetly needs to be painted or it will fade and peal in no time. Dont ask how I know. Id take it and have it sprayed by line-x, rhino, or whatever bed liner places you have. Just specify them to apply it thinly. I have seen some applied thick and others applied thin.

I would be careful what I used on the underside of the hood (fire safe) is what you need to think about as well as durability and appearance. I like SEM products as they fit the above criteria. Also you will want something that you can freshen up easily if things start to look a little bit like this was done 5 years ago, if you know what I mean. SEM makes a textured paint product as do allot of other companies.

High heat paint is really not a big concern as the factory never used it and most paint will handle the heat generated in an engine compartment.

esll.
