undercoating

[Mongo316]

hey there well I should get the 67 stang coupe back from the paint in about a weeks time and am thinking of powerwashing the underside and using undercoating. Not sure what type of undercoating to use? now the car will not see snow or rain but I want the undercarrage to be black... Just woundering if any one would like to share a few thoughts, would be great

eastwood sells a rubberized undercoating and most auto parts stores sell undercoat paint.

All I have to say is use POR15. That stuff if hard enough to stop rust, and it is tougher than nails.

 

[65 A Code]

if you use POR15 on the underside, do you need to paint over it?

Apparently not, as it isn't directly exposed to UV radiation, which is what destroys it. It would probably be good insurance though.

Eastwoods all the way!

Go to eastwoods.com and read the idependent comparison done by a car mag between por15 and their rust encapsulator....

I would use eastwoods...as a matter of fact I am ordering it up as soon as my car gets back from the exhaust shop getting the floor pans in...

I'll be doing the complete floor pans and interior (areas covered by panels) with their rust encapsulator. Once it is painted I'll be doing the underside in it also and using the undercoating in the wheel wells.

Go check it out...

I agree with the rust treatment, but I don't like undercoating, I use chassis black on all the hidden places, it's easier to detect flaws in the metal than with undercoat. If rust starts under the undercoating it isn't visible until it's too late, where with the chassis black it's easily seen before it gets bad.

I'm surprised no one has recommended doing the undercoating, or whatever you decide on BEFORE painting. That's what I would have done.

Just got a new eastwood mag today that stuff does sound pretty good. Anyone that has used know how much area you can cover with a can of it and is the aerosol any better or worse than the pint or quart brush on?

Ya, i did mine after I sprayed the interior and trunk area. No need to tape anything off at that point.

POR

The PO used POR on my 66 'vert. I can verify that it is very tough. It's sort of semi-gloss black and looks good. I had trouble getting it off of the rear end that he had also painted. POR even stood up pretty well to a sandblaster. I eventually had the rear chemically dipped to get the stuff off. Just my 2 cents, but undercoating sort of scares me. Every time I see it, I think someone is trying to cover flaws. I once examined some fresh goo that was covering a deli tray and self tapping screws. Even worse, I fear that it may hold moisture.

I use rustoleum....satin black mixed with a little bit of thinner....works perfectly and protects well also.

Two guys in town did their bel airs like that and they are beautiful.

I tried searching on the web, but couldn't find it. What's eastwoods address?

I tried both http://eastwoods.com and http://www.eastwoods.com and the first one doesn't work and the second is under reconstruction.

I have'nt seen anyone use undercoating for years. The stuff holds in moisture the causes rust. I live in PA and they use alot of salt here, even the new cars they dont have it and they dont recommend it. Come to think of it I have'nt seen a commercial for undercoating for many years.

 

[Mongo316]

thankls guys for all your help but all i want to acheive is a nice black bottom and wheel-wells

JC Whitney has some rubberized stuff that is in a spray can.

Sorry, that I did not chim in earlier, I used the 3M undercoating in spray cans and it worked great. First I used a rust preventative paint like POR or Eastwood than apply the undercoating. This is not like this paste undecoating that everyone has seen on older cars, it is like having black textured paint, thin and looks good.
