Yes, there is a simple way to put sticky-backed deck patches on. It sounds a
little stupid but really does work well.
Take a little liquid soap in a screw top pot (one like the pots in our boats)
and dilute it about 10:1. Use your finger to spread it all over and around where
you are going to put the patch. Peel off the patch backing and place the patch
on the deck. The soapy water will allow you to move it around, lifting as
necessary, until it's in the right place with no wrinkles. In the workshop here
it will dry in a few hours. In the summer, in 30 minutes. Replace the lid on the
pot and keep it to use next time. Of course it won't work during the racing
except at lunch break or a sunny climate!
