Sorry if this has been discussed elsewhere, but I was not able to find a relevant thread.
I have taken over a FFP Celebrity project on which I intend to mount a Rotec 2800. I intend to strengthen the firewall bulkhead and side structure in the first bay to accommodate the weight and power of the Rotec. Unfortunately, the original builder used a varnish, System Three Clear Coat I think, over lumber I need to glue to. I will be using T-88 (made by the same company, I understand) for the structural additions.
How best to prep (or remove) the Clear Coat?
Will sanding the surface provide sufficient bonding of the T-88?
Should I try to remove the Clear Coat entirely?
Perhaps with MEK or another solvent?
Thanks
