Por 15 on the underside

I put por 15 on the underside of my car. It looks pretty good. I am trying to decide if I still need to use the herculiner. I am going to insulate the inside with sound deadening.

If you have POR 15 on the underside, and you are putting the sound deadener on the inside - call it done. At that point, you won't really gain very much add'l sound insulation and the metal is protected. Even the rocks that hit the bottom will have most of the tin noise battened out with the sound insulation on the inside.

Unless you just want to go totally nuts. Then put the bedliner on both sides AND the sound deadener. You know, like nuking it from orbit - the only way to be sure.

putting on POR15 on the underside of a fiberglass car is not worth the $$.

i painted mine gloss black marine enamel (waaaaay cheaper).

for sound deadener - you can get that foil-backed buytl (sp=?) they use on flat roofs. check TheSamba.com for reviews / install photos.

the bay window forum has lots of great ideas as these guys (and girls) camp in their vans.

Just to clarify this is just the pan. Thanks for the help.

Urr aa If you find your car in a gravel driveway . and it chips the underside ..We warnned ya.. I uses a good urethane epoxy bed liner coating on both the pan and the underside glasswork.. and it looks more like Factory VW when put on with a 2" roller

It (WILL) give you extra protection.. if you stay away from Gravel your fine But out in the boonie? (Like where i live) I DO recemend it

I think im going to leave it alone and deal with it later if its a problem.

If it's POR15 on the bottom, the gravel won't chip it.

That shit is a complete pain in the ass to take off. Hate the stuff. But if you want something that STAYS on, that's the product.

Thanks for the help deciding guys.

Cant stand the color of this por 15 I have.  It is really shiney.  Has anyone spray painted over it and has it help up?  What is the best spray paint you guys have used?  Looking for a flatter looking black.

POR 15 has another product used as a second coat called a tie coat. I used it on the pan for the speedster I am working on. It bonds to the POR 15 allowing you to the respray with another paint.  From some past projects I found other paints don't stick well to the POR 15.  Check their website for complete directions and use.

If you don't top coat POR15 before it cures, paint won't really stick to it. You can rough up the surface with sandpaper to give it some bite and hope for the best, then go with that tie-coat stuff too.
