White Primer | Pulling Tape & Feathered Edges

When the white primer had fully cured I sanded it with P220 and pulled the masking tape. 

This is what it looked like.

This is the transom.

It is so much easier to paint both sides and the transom at the same time.

However, I got a surprise when pulling the blue masking tape. The tape pulled off a piece of fibreglass cloth, like this.

Exploration with a knife revealed that an old patch had clearly failed to bond properly, and had failed.

Oh dear. I sanded off the loose material, leaving this.

I will have to apply another patch or simply seal the substrate properly with clear resin.

Then I carefully feathered the edges of the primer with a P220 grit to remove the 'step' and make it flush with the substrate.

This is what it looked like.

Next is grey primer. Hooray!
