Prepping for Rustolium Paint - Filler

[bmouthboyo]

After extensive welding repairing windows, corners, channels, panels,etc I will hopefully be preparing my van for a roller job in the next few weeks and I want to make sure I know what is the correct method to apply filler etc.

Am I right in thinking I clean back to bare metal, apply thin amount of filler to a larger area than the dent etc, then use a flexible rule to remove excess, allow to dry (not sure how long), then flat back (not sure what grit?). Any need for a stopper?

When done should I prime as it will be a long process pepping the whole van? if so what's best to prime with?

Also the previous DIY owner seemed to have slapped thick paint all over! And i mean all over, rubbers too . should I try and remove all this to original paint with a DA sander? Or just key and feather any obvious edges / marks?

Cheers guys

There is just so much on the net about using filler and prep, its simply not worth expanding upon here. Youtube should give you plenty of info for starters.
