: An earlier thread addressed using a scraper - lots of folks here
: seem to prefer that route. I used a padded disc on a drill, 60
: grit - worked great! then finished up with a handsanding (only

: to external standards.

: I noticed your comment, BillHamm - you don't use a scraper, either?
I used a surform file to rought cut the inside of my petrel and then sanded very good results
