Fibreglass problem
This is very interesting, since the reason most old car people began to use
the DOT 5 silicone brake fluid was the safety of using it around car finishes. This is great (sarcasm), since I have a car with the fender down to factory primer and had the master cylinder blow DOT 5 all over it while trying to pressure bleed the MC.

Never thought of the coupe having had the fluid changed and paid dearly for not paying attention. As I said in the earlier post you need to eliminate as much of the silicone as you can and then cover the effected area with a tough coating, epoxy resin and/or self etching primer. Anything that can break surface tension as well as silicone needs all the attention you can give it before you try to color coat. On metal and fiberglass I still flash out the area with a torch as a start to kill its affect on adhesion and then clean while still hot. On the '66 the paint started breaking up just as I was finishing the first color coat and it had to be washed down and prepped all over to even consider another color coat. |

Normally, I never give it out. Too many spam bots pick them up and flood
the mailboxes. I've had a couple of addresses I've had to shut down as they got several hundred spam a day. And on the public newsgroups, I've seen people bombarded and harassed too much to give it out too casually. What's up?
