Coating over penetrating Epoxy

2 posts in this topic

I have replaced the Stringers in my boat. In an attempt to waterproof the new stringers I coated them with total boat penetrating epoxy. I have read where people are able to gelcoat over epoxy that has been cleaned of amine blush and sanded.  From limited knowledge I think Gelcoat is a polyester product .......... So can i layup fiberglass and csm/biax  to tab the prepared (washed and sanded) epoxy coated stringers ?  Is there an added step ?  or do I have to stick with 5:1 for the tabbing. and encapsulating , after  also cleaning and sanding. .........

To use polyester over epoxy we recommend washing and scrubbing with water.  Sand with 80 grit and wipe well with acetone.
