I only brush it on.
One inch wide super soft sable brush...used ONLY for Future and nothing else.
I apply front to back keeping a wet edge......cover model ONE time...do not go back to covered areas. A 2nd coat if needed after firs dries 100%.
I apply enough for nice wet look but not dripping. If to much is applied wick off excess at bottm with paper towel.
No ill affects on decals (including ALPS), chrome or clear parts.
I allow 24 hrs min before handling.
Started using it in 1984....never looked back. thx
