What are the tricks/methods to properly skim coat panels? I've skim coated my entire hood with Marson Platinum using a 5" spreader (or maybe it's a 6"), beginning at the center of the hood and spreading to the edge of the hood so I'm moving perpendicular to waves. I have maybe a half inch of overlap, or maybe an inch by the time I work it a little bit and try to blend them together and smooth them out.
I then go over it with 40 grit DA to knock down heavy stuff like ridges, etc. Then hit it with 80 grit DA to remove some of the body.
I guidecoat then block with my 16" durablock board with 220. It works well with the Platinum because it sands easy, and I don't have any adhesive rolls for lower grit and it helps me from taking too much off. I guidecoat again then block again.
I still feel waves even though metal is beginning to poke through in some places and I'm sure these are probably resulting from where I began a new spread.
Could use a little help here! What are your methods? Thanks.
