Hey guys,

I have very special car that I'm going to repaint. It was featured in the April issue of Sport Compact Car. I have bought every color in the quart cans that duplicolor has, mainly because I have some testing to do and have had a hard time making a decision about the color scheme. Plus the car has a 70s vintage Martini Racing style paint scheme (white, blue, black, silver).

Here's what I know. The car is a 1973 Porsche 914 with a fiberglass 934 can am wide body kit. The doors, hood, trunk lid are the original metal. The front nose, fenders and rear bumper are fiberglass that is at least 30 years old. Some of the fiberglass has some cracks and spider webbing that I have to fix. The entire car was repainted in the late 70s and was originally acrylic laquer from Porsche. I think the repaint must have been with acrylic enamel because it does not tend to oxidize like lacquer. However, some of the underlying paint (probably the original) has begun to seperate and spiderweb.

My question is this. Knowing that Lacquer may lift enamel, is there some kind of sealant that can be applied to prevent that from happening?

Ed, very cool car! Unfortunately you are going to have to strip off all existing paint and start from bare fiberglass/metal. The reason for this is because any spiderwebbing that has started from aging of the original paint will come back through any new paint. I had this happen with me with my own personal car hobby at home. The only other way to stop this is to spray a few coats of a filler primer and block sand it smooth a few times to fill in any imperfections. As far as the Paint Shop lifting being a Lacquer, you should be ok since the existing paint is so old/hardened. I hope this helps you.

I agree about building up and wetsanding between coats, As I recently posted I just primed my 68 GTO with PS primer, some areas had "cracks"
I just sanded and added more primer until they were filled, I did however need to use about six quarts of primer for the job.
