Repairing a few 'dry spots under gelcoat after vacuum infusion molding

Hello folks . . .

I am nearing completion of my 'DIY' fiberglass extended swim platform, having taken the part out of the mold this past weekend.  I posted a thread (or 2) a few months ago about slowing the cure time of resin and wetting out biaxial cloth.

Picture of my new platform getting ready to install it on the boat . . .


In doing my QC check and tapping around the surface , I noticed a few 'dry' spots under the gelcoat.  I opened a couple of them and applied some resin and then gelcoat, but there are a few others that I have found using both 'tap' test and with a jet spray from a garden hose.

As such, I  still have a strong hold on my 'novice' status for resin infusion Crazy Tongue Smile

I am wondering if there is a preferred or easy way to repair these areas  - each one is a few sq. inches  (15-20 sq cm).

You can re infuse dry spots. Just do a mini infusion on the dry spot only.
