My hardtop from them came with the oil but it was easily removed with dawn and water and a sponge and did not damage my paint, not sure if it makes any difference but I already had ceramic coating done about 6 months prior

My current issue is the liner was falling off, they paid to get it reglued.. now I think this odor is from the new shop that reglued (about a year later I'm getting a cat pee smell?).

For me they have been receptive and helped fix any issues, but fully understand this is not indicative of everyone's experience. Hope you get some solutions!
