Light bulb access panel

[l6rth]

Hi all, I am wanting to cut an access panel in the chim wheel wells and thought of using this http://www.toolstation.com/m/part.html?p=44999, good idea? Or I have a multi tool I could make a square panel with, also where abouts should I cut with regard to retaining strength and is there anything in the way the I can't see until I cut through that may cause me to largen the hole and making a mess of it. Thanks

Any ideas on thickness of fibreglass in the well?

I have the older model with out the access panel and it is a pain to change bulbs but I'm having second thoughts as I'm sure the time I have done the mod I will have done the bulbs

Just what I was thinking phased, is it worth doing do you think?
