Varathane over Watco Danish Oil
I’m having a serious finish application problem under the following situation. Trim Wood is Vertical Grain Fir – Kiln Dried and stained with Watco Danish Oil products (One coat clear to condition the wood, two coats cherry color), the stained surface have died for at least three week under ideal conditions. Plan was to top coat with Varathane Professional Clear Finish ( satin #1100). I brush applied a first coat of Varathane diluted 10% with hi grade mineral spirits that was well stirred prior to start and during finishing to get the denser materials off the bottom of the can. Allowed the first coat to dry 6-8 hours under ideal conditions. First coat went on beautifully with a minimum of imperfections. Applied a second coat of the same diluted finish and in some spots the surface went on fine in others spots (a few square inches) crinkled up / reticulated . I tried a VERY light 220 sanding in some areas and others I applied on the freshly dried surface with no apparent differences in how the finish applied. I spotted the issue early so minimum refinishing is required. Any suggestions as to what is happening and how to prevent it from happening?

Just me so !NOT a expert!.. If my finish not right.. I use a worn out 3M green pad.. I blow out all the crap.. Dust and other stuff with my air compressor...
I buff off EVERYTHING I have a problem with wetted with the finish I'm using.. SOMETIMES turns out OK!
Danish oil, with or without color added, is approximately equal parts
of oil,varnish,and mineral spirits. Either the oil didn't dry completely in spots or more likely since you didn't sand between coats the varathane polyurethane varnish didn't adhere to itself. Polyurethane has problems sticking to somethings,including itsself, that is why the makers tell you to sand between coats. Unless you were able to wipe off the last coat you now have to strip it off.
