Good day:  Would you be good enough to review the work plan below for my 43 year old,full keel sailboat and offer any recommendations that may be indicated?  Many thanks


After sodablasting the antifouling, my sailboat's gelcoat was in poor condition.  Many areas thinned away to point where fibreglass was bare, and thousands of small areas (pencil lead sized) where it chipped out.

In the end, I decided to grind off the gelcoat.

Boat has been on the hard for 1 1/2 years now, and the fibreglass appears to be in good shape, with some minor pitting.  Perhaps the chips were blisters at one time (although there was no liquid in them), or perhaps the gelcoat was poorly attached over these small pits, and the blasting pulled it free.

My poor man's moisture test shows the hull to be dry.  It has been draped for last few months--just to be sure.

I have feathered the sanding into the bootstripe (see plan below)

I have washed the hull multiple times, with warm water and pressure washer (on "delicate").  I have sanded and washed again.  

My work plan from here:
Wipe with Solvent 202
Apply first coat of Epiglass, releasing a few stands and coating under the pads
Next day, I will epoxy the under the remaining pads
Apply Watertite to areas where needed-mostly at the turn of the keel where grinding was "challenging"

When time and weather permits
Sand the Watertite
Scrub/wash with soap and water 
sand with 80 grit
wipe with 202
Repeat Epiglass process

When time and weather permits, proceed to Interprotect process

For the bootstripe, I will make sure the Epiglass is only coated onto areas that have been sanded to either fibreglass or well adhered/thinned paint/primer.

I got as far as putting the first coat of IP2000E on the hull before winter set in (I didn't want to leave the Epiglass exposed to UV)

Now that I am prepared to continue with the build-up of Inter-Protect, and have exceeded the 6 months no sand guideline, is the following appropriate?

Sand hull with 80-120 grit (what is preferred grit?)
Wash off sanding residue
Wipe hull with solvent 2316N or 2333N

Recommence coating with IP 2000E

Your help is appreciated; as always

Cheers
Chris

Correction: I should have written "wipe down with solvent 202". Any thinning would be with 2333N.

I have hauled my boat after "season one" post hull restoration following the Interlux process that I have detailed in the previous posts.  I am pleased to state that there is no evidence of blistering or poor adhesion of the products.  So I guess I will call this project "complete", and "successful".Clap
Cheers
