I noticed when my car was on jacks that the rubberish undercoated was coming off in a few places in the left rear wheel well. my approach would be the clean off all loose material, wire brush it, coat with stuff that bings to/stops rust and then cover with some kind of undercoating. is this what you guys recommend? can you recommend the materials i should use?

If you do this task, do it right the first time. Instead of removing just the "loose" undercoating, remove all of it. Use brake cleaner to remove the under coat, which leaves original paint undamaged (underneath the goo). OR... Heat w/ gun, torch, etc, and scrape off w/ a putty knife. Then wire wheel, sand, etc. down to bare metal.
Por 15 the bare metal. Undercoat on TOP of the Por 15 (if thats what you want... I wouldn't (IMG:style_emoticons/default/smile.gif) ) This was done with a Propane torch and putty knife. (IMG:http://www.nwfreshmarkets.com/well.jpg) |

Get it off the car and dont put anything back on it. 90% of the sixes I see with undercoating (that get driven) have it bubbling off. The heat from the engine/exhaust make it difficult to keep the coating on.
I seriously suggest removing it all. Undercoating helped the first 20 years of the cars life.. now it hides rust underneath it. I would rather look under a 9146 and see a solid chassis than one with 1 inch thick undercoating on it. B |

It is a ton of work, but when you are done.. man it looks GOOD. I go WAY out of my way to find 914 4cyl cars that have no undercoating. I was told by another 914 guru that all the tubs where undercoated. I have bought 4 cars over the last 4 years that had no undercoating on them. Never had it. Never will.

The rear of my car has no undercoating. The front has a bit, but I started taking off the loose stuff a while ago. I think I took engine degreeser to the back, cant remember. I know I'll be painting it when Im done.

Havent looked for the bag (very little time at the shop over the last 5 days because I have been sick) which is why you see me here.. I dont have to "talk" with anyone. The car belongs to a customer of mine. I sold it several years ago. It is the car in the my avatar.
