Short version - Can I apply body filler over seam sealer (SEM #39777) that has been epoxied (SPI) ?
Long version- Car is a '39 Chevy that had the drip rails removed when the top was chopped, 15 years ago. Where the drip rails were removed needed a small bead of seam sealer
according to the original builder. Now, after 2 previous all-over paint jobs over the last decade and a half it is in my shop and there was some lifting on one side where the drip rail
used to be. I ground it down to find rust had bubbled the paint. I spot blasted the area ( about 1 inch by 16 inches) and discovered a small hole at the end of the area. The hole
was not from rust so I assume it was created during the top chop or drip rail removal, only about the size of a pencil lead. Owner did not want the hole welded up for fear of
possibly damaging the interior, which he did not want removed. I applied two coats of SPI epoxy. After 2 days cure I hit the epoxy lightly with 180, cleaned and applied a bead of
SEM #39777 High build self-leveling seam sealer making sure the small hole was adequately filled. After a 3 day cure I sanded the seam sealer to make it a uniform shape, cleaned
and applied one coat of SPI epoxy. Since the car has been painted twice (whole body skim coated with filler before first paint), where the area was blasted and re-sealed is lower
than the surrounding area, of course, and will need to be leveled up. Can I apply body filler over seam sealer that has been epoxied ? In 25 years I have never had this situation
and I am kind of uncomfortable to do it because I've never done it !
Thanks
