Just keep sanding, misting with paint to see the high spots and more sanding

also use a block, Don't use your hands, Only use hands on curved edges. Best off to do the curves first and then the flats after.

As said above speckle with black paint but also keep looking down the pannel and running your hands over. High build priming is wicked stuff aswell

ye i did think about using that kind of primer will get some tomorrow. thanks for all the help and info so far

Yep Ill second using a hard block method for the flats and you can carefully use it for the longer curves aswell.

Also, is it just me or is high build primer a really crap primer for paint to stick to?

Its always tended to chip easily in my experience.

Ive used acid etch primer primer and thats been much better for adhesion and resistance to chipping/cracking.

Donno dude, Hope not as half my tail gate is covered in the stuff lol. I was going to use 2 coats of Grey primer on top of it for the paint to stick to?

The high builds flatted to 600 wet and dry atm, You recon i should ruff it up abit with 240 or 400 for grey primmer to key to it?

high build is good to fill in all the little sanding marks as you can sand it down with wet and dry after, acid etch is a better surface to spray to, but you can an adhesion promoting undercoat that is nice and flexible

For the final rub down before spraying use grey scotch pads

Lol I did that, I used grey primer on top of the yellow stuff once and the paint adhesion is better, but the yellow layer will still be crack-prone!

Tail gate shouldn't be too bad as you dont get many stonechips on there

Personally Id just use high build in the areas that need it (dips,cracks etc) and use acid etch primer on the rest. then paint.
