Stoner trim shine.. Safe for engines?

[Kool_ZX3]

Well i love it for all the exterior trim on my car, best product yet. is it durable?



Next question is it safe for under the hood detailing??? Safe for hoses,valve covers,etc..



Also opinions on this product would be great :2thumbs:

i use it on hoses and valve covers. i find it to last a long long time too.
