An elderly friend has a couple of fibre glass garage doors that were painted

what to specify when getting them re-painted to smarten them up. It won't be

to ask for when getting quotes.

Reove any loose paint then I think the main point is to ensure any
"glaze" on the gelcoat is removed using, say, 400 grade wet & day.
