Default RE: How to paint a cowl?

ORIGINAL: joesabido

I want to change the color scheme of my WM Mentor, the cowl is fiberglass already painted.

What kind of paint should i use?

Do i have to remove the old paint?

Any advice is wellcome [&:]
If you will be doing any masking, I suggest using the 3M brand blue masking tape. What you want is the "60 Day Safe Release", not the 14 day safe release. The 60 day can be identified by a "paper" appearance, not textured, and on the side of the plastic wrapper there is an adhesive index. You want the "2 dot" adhesive rating. The 60 day release tape will not pull up underlying fresh paint. As with any masking, I suggest sealing the edge of the tape with a clear prior to painting to prevent/minimize any "bleeding".

Hope this answers your questions.
