I thought about posting this in http://forum.woodenboat.com/showthre...-Skiff-Reports but considered that a new thread might be appropriate. In that thread, John Welsford advocated a full paint job as opposed to epoxy coating plwood boats. In view of the ever increasing cost of BS1088 marine plywood, some builders are using cheaper but still WBP glued plywood in their builds. My questions are about the initial finishing and subsequent maintenance of these builds and I would be grateful for any views fellow forumites may have.
- I've heard that the use of a specialist epoxy sealer is better than coating with a general purpose resin since the elasticity of the sealer more closely matches that of the wood thereby avoiding (hopefully) the damage caused by a sharp impact as John descibes.
- Some dispense with epoxy sealing entirely and advocate the use of epoxy primer paint for the same reasons as 1 above followed by undercoating and two top coats.
- Back in the mid 60's when my late Father was building a Mirror dinghy #3129, the instructions said to paint the inside of the bouyancy tanks with primer only as the use of gloss paint in these in encourage condensation to form leading to rot. Is this true that only flat or statin finish paints should be used here? BTW, Mirror#3129 lasted well until it was destroyed during the Great Storm of 87.
- If a full paint marine system is used, is the use of a metallic primer, eg Al, to be prefered over a normal type.
- As always, a little TLC given often is better than major refurbishment.
