Hi Mike,

I recently coated my Lexus LX470 with GTechniq CSL/EXO in Nov '16 and then someone backed into the truck and dented the hood. The plan is to have the damage pulled out and have the hood painted and blended into the fenders I believe. How should I go about handling the body shop painting over the existing paint coating?

Should the coating be sanded off (removed) prior to going in for the repair? Can the body shop just paint right over the paint coating? Any additional prep needed for proper bonding?

Thanks!
 
Let the body shop know that you have a durable paint coating..they should know how to prep before painting.

I will be letting them know, my main concern was about the durability of CSL/EXO and the need to physically sand the paint coating to remove it.
 
CSL doesn't need sanding to be removed. The pro version of crystal serum does.
 
I don't know about sanding to remove it, but under normal circumstances the paint should be sanded, or at least scuffed, before a paint is applied.

The body shop will sand the coating off as part of the prep.

Sanding of course removes everything including the paint.

Good news is with a coating the overspray will be easier to remove.

If you don't think overspray will happen then clay adjacent panels before you take it in and then do a baggey test.

When you get it back , do a baggey test (bet there is overspray).

One time I took my car in to have a front fender sprayed.

I purposely waxed the heck out of the hood and door adjacent to the fender.

When I got it back I did the baggy test and wow.

Clay bar removed really easily because of the wax.

The wax provided the sacrificial layer to protect the paint.

Please be sure you tell the shop if you do this as wax/sealants and especially silicone do not play nice with paint.
