Tools for spreading fiberglass micro

[PaulvS]

I get excited by new tools (yeah I know...) and the latest discovery is that .035 thick clear PET plastic sheet can be cut to size with scissors to make a very effective spreader for epoxy micro filler. It is slightly thicker than a credit/hotel key card but is more flexible and can be curved and held at a shallower angle to get a better finish. YMMV!

I do a bunch of boat repairs. I routinely save old plastic orange juice and milk jugs. For me they are the right balance of rigidity and flexibility. Hotel cards are great for flat patches or really thick micro.

It's probably the same material, just thinner, I believe some jugs and bottles and containers are formed from PET plastic.

Another exciting discovery is that this material works very well as a flexible squeegee to push resin into pinholes after sanding.

Steel Filling Knives or Spatulas are also useful and quite inexpensive.

Thanks Cal. Yes I used a double layer of electrical tape around the edges. The Van's RV-14 canopy finishing video on Youtube was helpful.
