What kind of primer filler do you use?
ReplyDeleteHi Daniel,
DeleteI only use the Duplicolor Primer/Filler, available at auto supply stores.
The can label is now grey and black.
They have changed the label description again - it now says:
Duplicolor Automotive PRIMER Series, FILLER
Look for FP101 Grey Filler above the UPC label on the back.
It is worth the extra few dollars for this primer/filler. Some other brands are almost "rubbery" when you try to sand it down.
Good Luck!
