What did you put over the POR on the inside?

This is my biggest problem...

I applied the POR ChassisCoat Black Paint over the POR15 on the inside of the floorpans. This summer I will replace the tarmat stuff that I had to remove to apply the POR with something. Haven't decided exactly what to use yet. There was a Thread here a while back suggesting several options for the Tar Mat.

As I recall (I could be wrong) one was "Q-Pads", and another was "Dyna-Mat". I need to do more research before I settle on what to use.

Whats the finish on the chassis coat like?

Did you spray on or brush on?

Does it resemble paint in the sense that it is thin enough to show signs of future rust (well as much as 2pack paint would anyhow)

Thanks

only thing that will suck is once I put the por 15 down, I dont want any crap getting wet and molding or getting wet and taking a long tgime to dry

Finish was similar to the POR but without the sensitivity to UV, I brushed it on. Spraying their products requires special filteration for breathing and I don't have a compressor either. The ChassisCoat is similar in consistancy to POR.

If the POR has beeen properly applied, I don't think you would need to worry about signs of rust in the future. It is NOT as thin as regular paint though.

I have 2 coats of POR and 1 coat of ChassisCoat on the underside AND same on the inside of my floorpan.

You will need to make sure that your door seals are in good shape and stay that way. Also make sure that your windsheild seal is in good shape too.

POR or no POR, any water that gets down there WILL take a LONG time to dry and will cause the carpets, and any underpadding to get moldy.

The Dyna-Mat or Q-Pads shouldn't mold, but carpet padding and carpets will.

Do you have any photos you could stick in your gallery?

Sorry, No digital camera as yet. Spending all of my (limited) money on the car, and lifes surprises.

I did one floor pan late last summer, and plan on doing the other this summer. Maybe I'll get one of those new disposeable digital cameras and document the project.

For others, or for the initiator of this thread... I have seen a recommendation to use dry ice to get undercoat off. Apply it to the inside of the car where it can set without having to hold it to the surface. When the undercoat/tar is well cooled, it will chip off readily per the writer. I believe GrassRoots Motorsports had this article???

Becareful of getting a "burn" freezing your skin. It will happen "rightnow". Don't ask.

Rather than play around with heating and freezing etc i got right at it yesterday with a knotted wire wheel on an angle grinder. After about 2 hours I had done the outer half of the passenger underside and 3/4 of the passenger rear wheel well.

The work itself is not very hard, the hard part is manouvering yourself under the car. Now i see why people swear by rotisseries. I have the car up on 40cm jack stands and while it is adequate, it aint easy.

Also the dust/particles from the underbody go everywhere (as i was told as well), I had a face shield and breather mask and its still got all over my face and neck, hands and overalls. Spent a good 15 minutes cleaning out of my ears

Took a break today as I have to go out for dinner tonight, but hopefully will have it all done this week.
