I'll be making a
gelcoat repair to my
hull using the preval sprayer and considering not using tape to protect the rest of
hull from overspray. Using tape may leave a visible
line between the
repair and the rest of the
boat even if I was able to feather the
repair and turn the edge of the tape under itself, which seems like a good idea to lessen the chance of a hard
line. Since I'll be using 320 grit sponge, 400 grit and then 600 grit on a block prior to 3M imperial compound after the gel completely cures, it would seem that any overspray would be removed from the surrounding area?? Plus the surrounding area would not be sanded before the gel was sprayed and thus would(should) be removed easily via the
sanding and rubbing coupound.
One other question while I'm thinking about it. When using wax gel is a wipe down with acetone needed to remove the wax prior to
sanding? I read somewhere that just sanding will be sufficient in removing it. This if after spraying and I know that an acetone wipedown(2 rag method) is needed prior to spraying
