FORUM RULES: Users agree to these Rules when using Forum.

The site administrator reserves the right to change the terms and conditions of the user agreement without prior notice to the user. It is the responsibility of the user to regularly review the terms of this agreement.

The user agrees to the following terms:

All information that you provide to us for your membership is correct.
You will not use your membership to spam, harrass, or exploit other members in any way.
Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
Commercial-type sales postings will not be allowed.
No mass posting or flooding of the boards is allowed.
No Advertising of parts or cars; no Ebay or business/commercial ads (please use the "Classified" for ads Wanted or For Sale).
VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

http://donclink.com/deuce_75_1/images/dscn2950.jpg

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

My 35 car has a undercoating that was sprayed on the bottom of the body. I would like to remove. Does anyone know an easy way to remove it. Eastman has a spray solution in a can that I tried with no luck in it working.

The words "easy" and "removing undercoating" should never be used in the same sentence! If the substance wasn't sprayed over rust, etc, it is firmly attached to the metal, and will resist all attempts to get it off. We use a heat gun and a sharp scraper when we have to get to the underlying metal. There were two main types of undercoating: rubberized and petroleum based. Both will burn if a flame is applied. Any effective solvents, such as lacquer thinner or acetone, create explosive fumes with greater force than gasoline, and can't be safely used. More than one car has been destroyed trying it, not to mention serious or fatal burns. Many give up trying, and apply a fresh coat to improve the appearance.

Moxie, The easiest way to remove undercoating is to remove the car. I agree with Bob, it can be very dangerous. I still bear the scars of dripping burning undercoat that had to be pulled off my skin while still aflame.

Aircraft stripper works to help soften the undercoating ,but you sill haveto do A LOT OF SCRAPING
sanding disk on an air grinder works well after most of the undercoat is removed

I had the same problem on my 48 Woodie. Used a heat gun to soften up the undercoating and then scr*pe it off. Spray some mineral spirits or kerosene on the metal and use coarse steel wool to scrub the metal. It's slow but it it's the best way. I've restored four cars and have used the same way to remove undercoating. It works.

Vince has it right. The heat gun works great. Also, a car might have really great original paint beneath that under coating. Use a wood or plastic scraper at first to see what is there as a metal putty knife might scrape to bare metal. Worked on my 49.

Here's an after shot and you can see the other inner fender that hasn't been stripped. Note: this is the original Ford paint underneath the undercoating!
