Undercoating questions?

[bobswei]

I started doing research on undercoating my '72 911. I only want to do touch up areas since most is in-tacked. It looks like Wurth underbody sealer is the best match and grey is the correct color, (since beige is not made anymore?) First question, where to find the grey? I checked the Wurth website and they only show the black. Everywhere I look, only black. Next question, Is this easy to blend into the old undercoating or will it be obvious and I should coat the whole underside of the car?
I saw that the spray gun style creates the best match for texture so that is my plan.
Thanks for the help.

it's not undercoating that is the useless black crap that should never be used on anything .
you want to use chip guard .
U-pol is who makes it for wurth . u-pol offers it in white , gray and black it can be tinted to match your cars color / shade .
you would tint it with acrylic enamel .

OK, I found the u-pol fairly easily. This will give an original looking finish?
Also, will 1 liter do the whole underside of a 911? I would want to tint it to match the gray/beige of the original undercoat. Looks like I would be getting gray for the gas tank and white for the underside.
Thanks for the response....

They make it in a spray can now. Used it for touch up's and it works great

Does the spray can texture look the same as factory? Can the flow be controlled?

yes some what is does . you have to control the distance and speed plus the number of coats more to get the same OE look but it's very do able
