Actually, the frame did perform as designed. I recall from some of the books that the design life of the car was supposed to be 10 years (a long time in 1978). Daily driven cars probably had frames rust thru in about that time. you are now dealing with a 20-year old car. ANY 20 year old car that has been exposed to the elements has frame rust problems. I recall fixing damage like this on a 1963 Corvette, in about 1974 (driven in Illinois) Dave ----- Original Message ----- From: William T Wilson <fluffy@xxxx> To: <dmcnews@xxxxxxxxxxx> Sent: Thursday, April 06, 2000 1:43 PM Subject: Re: [DML] Rust On Wed, 5 Apr 2000, JDL wrote: > Wouldn't something like that end up having the same problem as epoxy, > in the long run? Probably not. The epoxy is a fairly rigid, brittle material which breaks when the frame flexes. Either the engineers thought it wasn't as rigid as it was or they thought the frame wouldn't flex as much as it does. In contrast, most undercoating style materials are quite soft and really won't break. (I don't know why they didn't use a standard rustproofing material in the first place).
