I have re-read the pinhole filling threads. I have large areas of smooth fiberglass on cowl, pants, canopy etc. that have not been filled with micro cosmetic work. The Dan H credit card pinhole process is compatible with small areas but leaves ridges that risk glass balloon fracture when sanding.
Also, 80 grit sanding to feather micro filled areas can leave abraided glass , a potential pinhole source ? Dan advises to not thin 105 with acetone. I have tested it over sanded micro and it feels great, but, no long term experience .
My curiosity is to prep pinholes with credit card, cloth/sponge wipe , sand “carefully” etc,
Then spray with thinned 105.. this would leave a finish for minimal 220 wet sanding ready for primer. Your thoughts ?
