1...Rub down with scotch brite pads, prep with green (course), then red (fine) to "key" the surface.
Clean/degrease (aceton, panel wipe)
2... Etch prime (3 coats) all the surface, leaving 5 mins between coats, leave for 10/15 mins.
3... Prime filler ( is just a "high build" primer & gives better cover) apply light coats leave 5 mins between coats rub down using red scotchbrite after the final coat to level & remove any scratches that may show though.
4...Top coat apply light covering coats leaving each coat to become "tacky" this will reduce the chance of paint running...when your happy with the finish walk away! "that the hardest part".
