Just Kampers Dynatek.. any good?

[Jason Kew]

Hello forum guru's..

I have some just kampers vouchers I need to use which is a great opportunity to get my van insulated!

JK seem to only use Dynatek, anyone used this, if so which mm did you use?.. it's quite pricey and I only need my rear tailgate and bulkheads doing (lwb) kombi

Thanks for all your help in advance
