Undercoating bottom of hood?

[muddpile]

Can I use undercoating on the underside of my hood? I'd rather a black textured look than orange painted, and I figure this is the easiest/cheapest way to do it. Will it handle the heat and stick good, or am I better off with something else? I have cleaned/sanded it multiple times, so it is well prepped for something. Thanks!

Personally I wouldn't do it, but if you have to use something I guess I would try a spray can bed liner, give some texture and will resist most underhood fluids. If oil or gas got on the undercoat you would have a big sticky mess of tar all over. My 2 cents..........

I have thought of doing this at some point, but I would take it to a rhino line, or some such place, dealer to be done by a professional. I thought it would help with the hood rattle. I have seen some of our hoods on 4x4's that run on rough roads all the time that have cracked as a result of flex. Maybe this would help?

I wondered about the oil and gas issue too... If I recall, it deteriorates this product. Thanks for the tip.

LOL!! i bought one truck and the PO found that yard sticks were good to cut down on the rattle. Anyone need a yard stick i have lots of them.

Would be hard to keep clean. The underside of my hood actually catches bugs. Mine is the same as the exterior. Those are my thoughts.

Mudpile , the bed on my dorf 250 has something like Rhino and I think it would be to heavy for the hood and springs , it's tough but it is like an 1/8 inch thick!
I have a remote spot welder and have been tossing around in my head to weld studs in to use insulation as a rattle dampner. Just a thought, RH

I used a piece of commercial felt carpet pad ( 1/2 -5/8 thick)...This pad is quite dense compared to the felt pads I have seen some years ago used in home applications. Used construction cement ( Panel adhesive ) in a caulk gun... applied the caulk in 1/4" beads spaced about 6-12 inches apart. I also used about a number of plastic push- in attach clips in the hood rib areas... Got these from a junk yard, these are used in some car trunks and hood liners to hold the sound deadening material in place.

Don't use the spray can bed liner. Used it on a firewall one time & it only last about5 months.

I'm a bit concerned also about the weight issue. My hood on my K5 vibrates a fair amount at idle and I would be worried about the effect of that extra weight.

What about por-15? Wouldn't be as thick and heavy as rhino liner and won't deteriorate if chemicals get on it?

[kawahawk]

how about a high heat flat black like for a weber grill?

[muddpile]

Hi heat spray paint was another thought of mine. Sound deadening and heat aren't my major concerns, but rather appearance.

I had a quart of black DuPont Centuri left over that I bought in 1986. Two years ago I used a 3M 'sandblaster' disk in my grinder to take the hood down to bare metal. I prepped that and sprayed it with PPG epoxy. Over the epoxy I sprayed the single stage black. Two years later it still looks good.

It is a dead bug magnetic howerver.

One more thing. I masked off the braces when I sprayed the black. Then masked the black off and sprayed the body color on the braces.

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.
