I would never reduce more than maybe 25-40 percent. Orange peel, uneven gloss, basically what Dennis said


I did a repair on a large panel and finally reduced over 100%, probabaly 150.

Night and day difference, I felt so stupid for not doing it sooner.


I have seen guys that can spray the 10% reduced mixture and get good results, mere mortals like myself....use the 150% mix

Just my opinion, I need every unfair advantage I can get while finishing
