I bought an Al Knock soft top kit for my 1954 about six years ago. I had the frame restored and top kit installed about six months ago and it looked great. Today, while I was cleaning the car, I noticed what looks like small white acne spots imbedded all over in the clear plastic. I tried using some warm soapy water on it, then a light plexiglass cleaner called Plexus but the spots are well in the plastic.

Anyone else have this issue...and is there a cure?

I would try Marine Plastic cleaner. It was most likely caused by mold. Check out a marine supply house. They have some excellent plastic polisher/cleaner products.

My son used the polishing kit for headlight lenses and the window on his '61 looks like new.

Fly 'dung, and they do the same to chrome and painted parts....keep them covered and frequently washed.........

I had the same problem with a top I got from Knoch. The cause is a mystery to me and friends that I have discussed it with. Al Knoch was not helpful in explaining the cause or offering any assistance in fixing the problem. Personally I think the plastic material is faulty (possibly too soft). If you find out what caused the problem, please let me know.

If it is mold - prob from putting the top down wet (or even just slightly damp). NEVER store your top unless it is BONE dry ! Mold is a huge problem here in Florida.

The top has been up since it was installed and I keep it inside my shop with a cotton lightweight car cover on it. Here in So Cal we don't have enough humidity for mold.
